The substance starts as a liquid and by the end will probably be a gas, through vaporization. The heating curve of water is going up and then reaches a plateau at about 55°C Then it goes to 95°C and then goes up to 115°C. By now it is most likely a gas since the temperature is over 100°C, Which being the boiling point of water, is when it begins to evaporate into a gas. so by the final time of being heated for 201 minutes, the liquid evaporated into a gas. The plateaus were when the water was slowly changing.There was o temperature change during any of the plateaus. At the first, the ice was melting into water. At the second, the water was warming from water to boiling water on it's journey to 100°C. At the final plateau, the water slowly, but surely started turning to a water vapor. I the heat would have increased, and the experiment would have carried on long enough, there would have been no water left in the beaker. This is because the water would have been completly evaporated.
The graph shown portrays The Heating Curve of Water. At point "A", the ice is warming up to water at 30 degrees (C). At point "B", the ice is becoming mostly water at 55 degrees(C). The temperature is not changing because the substance is undergoing a phase change. At point "C", the water is changing from water to vapor and it is starting to boil. The water is boiling throughout point "C" and white vapor is starting to emerge. At point "D", the water is starting to boil at 100 degrees (C). Then lastly, at point "E", the water is changing to water vapor at 100 degrees (C) or more. That is what the graph shown portrays.
The graph is the Heating Curve of Water. As the ice melts and the temperature rises. When the ice changes into water at around 55° C and it plateaus. The reason for the plateau is the energy is being put into melting the ice, so the temperature does not rise. When the temperature rises to around 100° C, the water begins to boil, and the water starts to become a gas. The reason that the temperature stops rising at around 100°C because it cannot go any higher because there is still water in the container, and the water is already a hot as it can get.
The heating curve of the substance on the graph would suggest that the substance is not water. At point A on the graph, there is a substance which is in a solid state. The solid starts at a temperature of 30 degrees celsius and immediately starts heating up. At point B (55 degrees celsius), the substance starts melting into a liquid. This process has completed at point C (82 minutes). Then, the substance in its liquid form starts to heat up. By point D, the substance starts to change phase from liquid to gas. By point E the substance has completely gone from liquid to gas. Beyond point E represents the heating of the gas. The temperature of the substance plateaus when it changes phase. This is because the heat being applied is not being used to completely heat the substance, but it is also adding energy to the substance for it to change the state of matter it is in.
The graph shows the Heating Curve of water. Point "A" is the ice warming up turning into a liquid at 30° C. Point "B" is the ice becoming mostly at 55° C. the water/ice is not changing temp because it is going threw a phase change. On point "C" it is starting to rise up from 55° C. At point "D" it is 90° C and is starting to go to boiling point. At point "E" is starting to go to a change which it is going to be water vapor.
The graph shown is most likely a representation of data collected of a solid being heated up. The solid could not be ice because the graph idicates that the substance reached 100 degrees Celcius (water's boiling point) and continued to increase. But, if the solid had been ice the graph would have reached a plateau because liquids begin to turn into a gas at their boiling point. The fist point where the graph reached a plateau was when the solid began to liquify. The reason for the plateau is because all of the substance's energy is used for the phase change. Then, the temperature of the liquid is able to increase for a while because it is no longer undergoing any phase changes.
The heating curve displayed on the graph shows that the liquid is not water. Water’s boiling point is 100°C so the line should plateau at around 100°C. Point A represents when the frozen liquid is first being heated. As it is heated the temperature rises to point B, the melting point. From point B to point C is when the solid is using its energy to melt into a liquid. Therefore there is no temperature change. The rise in temperature from point C to point D represents the liquid being heated into a gas. Point D is the boiling point where there is no change because its heat is being used to change the liquid into a gas. Point E is when the change is complete and the temperature can rise. If the experiment were to be extended the temperature would resulting in total evaporation and nothing left in the beaker.
This certain substance is a liquid and then vaporizes in to a gas. it plateaus a few times then after being heated for 201 minutes the liquid has evaporated to a gas. When there is a plateau the temp is not rising.
Well going from A to B it rises than from B to C it stay's at 55 degrees. Than C to D it raises from 55 to 90 degrees. Than D to E it stay's at 90 degrees and E just goes up.
This substance probably is not water, due to the fact that water reached around 97°-98° C in fifteen minutes, whereas this substance takes 82 minutes just to get to get warmer than 55°C. This substance starts at 30°C (point A), then rises gradually to 55°C (point B) and plateaus up till the 82 minute point (point C). It gets warmer again, it's temperature rising to 90°C and then plateauing again somewhere between the 82 and 160 minute points (point D). Once at the 160 minute point (point E), the temperature rises again to 120°C. This substance has probably gone through a phase change, most likely vaporization (water into gas). Or, seeing as how this substance may or may not be a liquid, multiple phase changes may have occurred during the duration of the experiment.
The graph shows many plateaus from B to C and D to E. These plateaus occur because, when a substance or chemical is changing phases, it's temperature stays the same. This happens because a lot of energy once used for heating the substance, is now diverted into changing the phase. Therefore these plateaus show the changes of phases in the substance. Also, there are only two plateaus this means there were two phase changes solid to liquid and liquid to gas. This substance may not be water but it is probably some kind of liquid coming from its frozen state. This solid starts at 33 degrees Celsius then, it eventually heats up to point B which is 55 degrees Celsius this is were it is most likely the substance turned into a liquid. Then it continues to C where the liquid is heated up which leads to point D where the liquid begins to turn into a gas which leads to E when the substance is a gas.
The graph shows at point A it is about 30°C, than increases to point B which is at 55°C. From point B to point C, there is a plateau which than increases to 90°C, otherwise known as point D. From point D to E, there is another plateau which than rises again to 120°C. The plateaus show a change in phase because during a phase change the temperature does not change. This is because the temperature heats the the molecules that bond the solid, liquid, or gas breaking the bond. The energy is changing the phase not the temperature. This is the heating curve of water because from point A to point B the ice is becoming hot enough to turn into water. From point B to point C the ice is going through a phase change to water. Point C to point D, the liquid is warming. Point D to point E the water is almost boiling and is vaporizing. From point E and beyond, the gas is warming.
The graph shows that the substance that is being heated starts as a liquid then gets heated until it reaches a gaseous state. The temperature starts at around 30°C and the first plateau is at about 55°C the liquid keeps heating until it reaches its second plateau at about 90°C. The liquid is still rising until it reaches another plateau at 120°C. Because it has heated to such a high temperature it has probably reached its boiling point and is starting to turn to a gas. During all of the plateaus the temperature stayed at a constant temperature then rose quickly.
The graph shown shows the heating curve of water. It starts as ice (A) at 30°C and heats to 55°C (B) where it becomes water and is a plateau for a little bit. After a while it starts to heat up again causing the water to starts boil a little bit but not yet producing water vapor. At point "D" where it is 90 degrees the water starts to bubble more rapidly, starting to produce water vapor. Then after point "E" the water is rapidly boiling producing lots of water vapor while rising in temperature.
This graph shows that the substance that is being heated is not water. It is not water because waters boiling point is 100°C, and when the substance reaches 100°C it shows that it keeps getting warmer. If the substance was water, it would plateau at 100°C. At point A the substance starts at a temperature of 30°C, and keeps rising until point B where it stops at 55°C and plateaus. This is because of a phase change from solid to liquid. Then it raises in temperature again at point C, until it reaches D and plateaus again at 90°C, due to a phase change from liquid to gas. Then it continues to get warmer, after the plateau.
The graph shows us that the substance can not be water because of the two plateaus. The line begins at about 30 degrees celcius and reaches the first plateau at 55 degrees celcius. Then the line starts to rise again until 90 degrees celcius. Finally, the line rises until it reaches 120 degrees celcius. Every two letters, the line plateau and dosent rise till the next letter. Also, the line begins with rising and ends with rising.
The graph given exhibits The Heating Curve of Water. At point A, it is slowly melting at 30°C until it reaches 55°C or point B where the matter is mostly created from water. Here, it reaches a plateau. Then it moves to point C, or 95°C, and then point D at 115°C. In this course, the temperature does not change since an undergoing of a phase change occurs. When is becomes boiling water at point C, it starts to become water vapor. At boiling temperature, the water boils at point D and then moves to point E, it turns to water vapor at a quicker pace. If is was continued, there would be no more water left since it would have all become water vapor in the end.
What is happening here is that ice is being heated by a flame. The temperature starts slowly rising at the beginning, then reaches a plateau as the ice melts into water at 55*, when the ice can't take any more energy. The temperature then starts to rise again as the water heats up, then reaches another plateau as it starts to boil, when the water starts vaporizing at the bottom (where it's the hottest) at 95*. The temperature then starts rising again as the water slowly starts to vaporize completely, and reaches the final plateau as it completely turns into a gas, at 115*.
What is happening here is that a solid other then water is being heated by a flame. The temperature starts slowly rising at the beginning, then reaches a plateau as the substance melts into water at 55*, when the solid can't take any more energy. The temperature then starts to rise again as the water heats up, then reaches another plateau as it starts to boil, when the liquid starts vaporizing at the bottom (where it's the hottest) at 95*. The temperature then starts rising again as the liquid slowly starts to vaporize completely, and reaches the final plateau as it completely turns into a gas, at 115*.
Between points A and B, the substance is in solid form, and it increases in temperature from 30°C to 55°C. Between points B and C, the substance goes through a phase change by changing from solid form into liquid form, so the temperature remains at 55°C. Between points C and D, the substance is in liquid form, and it increases in temperature from 55°C to 90°C. Between points D and E, the substance goes through a phase change by changing from liquid form into gas form, so the temperature remains at 90°C. From point E until the end of the experiment, the substance is in gas form, and it increases in temperature from 90°C to 120°C. This substance is not water because its boiling point is 90°C, but water has a boiling point of 100°C.
The substance in the graph is not water for a multitude of reasons. For example if the substance was water then around 100°C the temperature would hover instead of continually rising. At point "A" the substance in it's solid state is starting to be heated and is beginning to steadily rising. At point "B" the graph shows a plateau portraying that there is a phase change occurring, from solid to liquid. At point "C" the phase change is finishing and the temperature is beginning to rise again. At point "D" there is another plateau, and another phase change, from liquid to gas. At point "E" the phase change is finishing and the substance is now a gas. To conclude,this graph does not show the heating curve of water because of at what temperature and when the phase changes occur and after the substance hits the 100°C point it continues to rise.
The substance is in solid form between points A and B.It increases in temperature from 30°C to 55°C.The substance goes through a phase change between points B and C. The substance changes from a solid into a liquid, therefore, the temperature remains at 55°C. The the substance increases in temperature from 55°C to 90°and it is still in liquid form. Between points D and E, the substance goes through a phase change by going from a liquiq into a gas.The temperature remains at 90°C. Until the end from point to point E, the substance is in gas form, and it increases in temperature from 90°C to 120°C. The reason why this substance is not water is because its boiling point is 90°C, however, water has a boiling point of 100°C.
The graph shown can tell us many things. First, we know that the graph is not data collected from water. We know this because the boiling point of water is 100 degrees Celcius, and the substance starts changing phase way before then at 55 degrees Celcius. The data being collected does not have a boiling point of 100 degrees like water, therefore cannot be water. Throughout the time that the data was collected, the substance was heating up gradualy and by doing so changing state or phase. The substance heated up slowly, because it took about 41 minutes to start changing phase and to heat up to 51 degrees Celcius. Point A is the starting temperature, 30 degrees Celcius. Point B is the beginning of the plateau of a phase change. Point C is the end of a phase change. Point D yet again is the start of a phase change, and the point E represents the end of the change. With this we can observe that the melting and boiling points for the substance are not very high, and that depending on how hot the heat source, the substance does not heat up very easily either. This is what we can observe and infer about the heating curve graph.
This substance started out as a solid (point A). As it is heated up, it is turned into a liquid (point C) . After the liquid phase, the substance is heated into a gas (point E). In between each of these phase changes, the graph plateaus. This substance could be water because it starts out in a solid state (ice).
In this graph, a substance is being heated. At letter A, the substance is in a solid phase at 30°C. At letter B, the substance reaches its melting point, 55°C and starts to melt into a liquid. The temperature does not increase because the heat energy is changing the bonds between molecules, not heating up the substance. At letter C, the substance has finished melting into a liquid and begins to heat up again. The heat energy has finished changing the bonds between molecules and therefore begins heating up the substance. At letter D, the substance reaches its boiling point, 90°C and starts to evaporate into a gas. At letter E, the substance has completely evaporated into a gas and the temperature starts to increase. This substance is not water because water’s melting point is 0°C and its boiling point is 100°C but this substance’s melting point is 55°C and its boiling point is 90°C. If the substance was water, it would melt and boil at the same temperature as water.
This substance is slowly turning into a gas from it's liquid form. the plateaus indicate the phase changes. At point A (30 degrees), it has reached it's first phase change from solid to liquid. It's next phase change is point B where it starts to change from a liquid to a gas. Between Points C and D, the water starts to near towards it's boiling point, and then it will just stay the same because it is at its highest temperature.
This represent the heating change of water. At point "A" the ice changes to water. I know this because the temperature is at 30 degrees (C). It then reaches a plateau at about 55 degrees (C). It then reaches 115 degrees (C). It i now a gas, because it is over 100 degrees (C). When the temperature was even, of in a plateau, the phase changed from one form to another. For example, when the water hit 30 degrees(C), it was changing from a solid to a liquid.
In the graph it start out at 30°C
(point A). The temperature take some time to rise. At 55°C (point B) it reaches a plateau and stays there for till point C. The temperature still stays at 55°C. Then it starts to rise at around 82 minutes. It slowly rises to 90°C (point D) to form another plateau. It stays there at about 160 minutes (point E) with the same temperature of 90°C. The substance is not water because of the time to substance took for the temperature to rise. Also at the temperature the substance was heated it would have completely evaporated.
The graph shows that the substance that is being heated starts as a liquid, then gets heated until it becomes a gas, through vaporization. The temperature starts at around 32°C and the first plateau is at about 55°C. The liquid keeps heating until it reaches its second plateau at about 93°C. The liquid is still increasing until it reaches another plateau at about 118°C. Because it has heated to such a high temperature, it has reached its boiling point and starts to turn into a gas. During all of the plateaus the temperature stayed at a constant temperature, then the temperature rose very quickly. The plateaus signal that a phase change is a occurring and overall the graph is showing a temperature vs. time change as a substance goes through two phase changes as shown by the two plateaus.
Whatever is being heated is getting hotter from A to B, staying at the same temperature from B to C and then getting hotter from C to D. This could be caused by many things,such as stopping the heat at certain points.
At each flatline in the graph there is a phase change. The substance started as a solid and changed to a liquid, then from a liquid to a gas. At point A it is as a solid, and is increasing in temperature. At point B, the solid is starting to change phase into a liquid. At point C, the liquid is accumulating heat, and at point D, the liquid is changing phase to a gas. And finally, at point E, the gas is still accumulating heat. This is not water because waters boiling point is at 100°C, and its freezing point 30°C.
The substance could be water, or it is another substance that is capable of changing phases as easily as water. The graph starts above 0° so if it was water, it could not be in its solid form. The heat of the substance inclines at the same rate and stays constant for the same amount of time. By the end of the graph, the substance has most likely turned into a gas.
From the Graph shown I am able to see that temperature of the substance in the graph is being heated. I am able to see that the temperature from A to B goes up, then stays the same from B to C, Goes up From C to D, stays the same from D to E, and rises again from E. When the temperature goes up. It goes up by 25°C. When the temperature stays constant it is on a whole number. The process took place for more than 160 minutes. This is probably not water, because in the Heating Curve of Water Lab the ice melted into water, whose temperature went up steadily.
The substance in the graph starts out as a solid (A), and the heats up to the temperature where the substance liquifies occurs (B). once the phase change is complete, then the substance, now in liquid form, continues to heat up (C) until it begins to vaporize (D) After that is finished, then the substance continues to heat up, now as a gas. At each letter, a phase change is either beginning or finishing. I don't think that this is water because I know that water's melting point is 0°C, and water's boiling point is 100°C and this substances apparent melting point is at bout 30°C, and boils at about 90°C.
The graph shown show the heating curve of water. Their are many plateaus on this graph. First at 30°C the water begins to heat. Then at 55°C the water reaches a plateau. In the plateau a phase change occurs, without any heat gain. At point C the water changes from water to vapor. At point D The rest of the water finally fully boils and turns into completely gas. Then the water is completly evaporated.
The substance is in a solid form between point A and point B. The points increase in temperature from 30°C to 55°C. A phase change happens between points B and C. The substance changes into a liquid, and then, the temperature remains at 55°C. The the substance increases in temperature from 55°C to 90°and it is still in liquid form. Between points D and point E, the substance goes through a phase change by going from a liquiq into a gas.The temperature remains at 90°C. There is a reason why this substance is not water. This reason is because its boiling point is 90°C, but water has a boiling point of 100°C
This graph is about the phases of water which clearly shows how water starts as ice and ends up evaporating. The nice thing about this graph is that it shows you four points. The first three points is a physical change. Because point A is ice (30 degrees celsius). Point B turns into water (55 degrees celsius). Point C turns into boiling point (95 degrees Celsius). But point D is a chemical change because it turn into (115 degrees Celsius) which the water turns into mist, which the mist evaporates. This graph is really nice because it clearly shows you the heating curve of water.
The graph's data suggests that the substance being heated up is not water. This is because the graph shows phase changes at times that are not proportional to water. Phase changes can seen when the graph goes into a plateau. The points within the graph where the temperature rises indicate times when a substance is heating up and preparing to go into a phase change. The substance in the graph had phase changes at 30°C, 55°C, 90°C, and 120°. Water goes through phase changes at 0°C and 100°C. The times in the graph, because of the previously mentioned reasons, is NOT water.
This graph indicates that on the plateaus, the substance being tested in changing phases. For example, on line BC, it is flat, so it is probably changing phases at that point. The same thing is happening on line DE. In the beginning, the substance was a solid, then melted to a liquid, and once it reached 100°C, it vaporized into a gas. This is the reason for the plateaus on the graph.
The temperature of this graph goes up as it heat up and plateaus when the substance goes to gas phase. this substance as you probably know is not water because at each point the temperature cools down as it transfer to gas to make a plateau and so on.
The substance starts out as a liquid and then will progress up to its boiling point and turn into a gas. The heating curve of water reaches a plateau. When it reaches about 100°C it will likely be a gas. Point A is ice and then B turns into a liquid the plateaus happen when the temperature slowly changes. Then when it hits point E it will probably turn into water vapor.
The graph shown is The Heating Curve of Water. At point A on the graph, the water is in its solid form. The ice starts at a temperature of 30 degrees celsius and starts to heat up. At point B (55 degrees celsius), the ice starts starts to turn into a liquid. At point C (82 minutes) the ice is completely melted. Then, the ice in its liquid form starts to heat up. By point D, the water starts to change phases from a liquid to a gas. By point E the water has completely gone from liquid to gas. After point E represents the heating of the gas. The temperature of the substance starts to stay around the same temperature. This happens because the heat that is being used to heat the substance is also giving the substance energy, so it can change its phase.
The liquid starts at an average temperature, but the longer it stays on the hot plate the hotter it gets, even if the Hot plate stays the same temperature. As the water gets warmer, The graph goes up a ways then stays at one temperature for a while, and then goes up more. For example, A goes to B than stays consistently the same for a number of minutes, and than rises up to C, and stays consistent, then up to D.
The substance starts as a solid and starts to melt. The substance is now a liquid after 82 minutes. Then the liquid starts to heat and then at point D is in the phase of turning into a gas. At point E it turns into a gas. Past point E, shows the heating of gas and the process of turning into the next phase, Plasma. The substance is water just by looking at the graph. This is because if you remember it takes awhile to heat and then grows until it slows at the end this is exactly what it looks like.
Well probably When the substance is at point a it is a solid and then when being heated it climbs its way up to 55 where it starts to become a liquid probably so during the phase change the temperature doesn’t go up this must be a substance that is not water but changes into a liquid at point c all of the solid has turned into a liquid completely then returns on its path to raising in temperature then once reaching point d it changes phases then gets to point e the liquid substance has completely turned into a gas and then at the end the gas just gets heated to 120° C
In the graph the substance starts to heat up, which is shown in the graph. Then it goes through a phase change. I can tell that because the temperature does not change. During phase changes temperature does not change which is why I inferred that the substance went through a phase change multiple times. I can then infer from the graph that substance was a solid that turned to liquid that turned to gas. At the end of the graph I can assume that the gas vaporized.
the graph shows The Heating Curve of water and it takes a reading every 82 minutes. At 82 minutes the temperature was at 55°C. The A,B,C,D and E show how much the temperature keeps going up. This shows the substance is not water because it started at 30°C and stopped at 120°C it would have stopped at 100°C if it was water. It probably turned to vapor by now. There are 4 plateaus and each go up about 45 degrees every time. The water would have boiled faster than that.
I notice the substance starts out as ice. I also notice that from A to B, the temperature increases, but from B to C, there is a plateau, which means the solid is melting. From C to D, the temperature increases, and from D to E, another plateau happens, meaning the liquid is boiling. Also, from C to D, the ice is starting to melt into water.
This line graph shows the heating of a solid so it shifts phases into a liquid, then a gas. The two plateaus in the graph are the phase changes. The first is the change from solid to liquid at 55°C (letter B) The second from liquid to gas at 90°C (letter D). The lines in between these points are where the object is being heated. This graph does not show the heating curve of water, because ice, (the solid form of water), cannot form at 30°C, which is where this graph starts (letter A).
This substance probably is not water because the freezing point of water is 0°C and the boiling point of water is 100°C. At 55°C the substance begins to go through a phase change because the heat stops rising for a period of time. At 90°C the substance goes through another phase change because the temperature stops rising again. This substance is not water because water does not go through a phase change at 55°C or at 90°C. Also, water heats much more quickly than this substance. Water reached 100°C in about 11 minutes while this substance takes over 150 minutes to reach 100°C.
The substance probably starts as a liquid and will be heated, until it turns into a gas. the temperature starts at 30°C and rises to 55°C, which is its first plateau. Then its next plateau is at 90°C. Then it rises to 120°C. 120°C is probably its boiling point, and since the temperature has reached over 100°C it has probably turned into a gas. At the end of the graph I assume that the gas vaporized. At the end of the graph I can assume that the gas has vaporized. The plateaus signal is that a phase change is a occurring.
The graph shows the Heating Curve of Water. At Point A the water is a solid, it is ice. The Temperature is around 30°C. After Point A the graph starts to plateau up to about 55°C. At this point the ice has started to melt away. At point B which is the next point the upward slant levels off and stays at 55°C. This shows the phase changing of the Ice to water. During a phase change the substance that is being heated does not heat because all of the energy goes into the phase change. When the graph Hits Point C it starts to slant upwards again. The phase change is completely over the solid is now a liquid. At point D which is approximately 90°C the same thing happens the water starts to change phases but this time its changing from a liquid to a gas. Again the substance stays at the same temperature because it is changing phases. After the phase change is complete the graph starts up again at E. This graph shows Water changing from a solid to a liquid then finally to a gas.
The substance starts as a liquid and will change into a gas by vaporization. The heating curve of water is going up and then it reaches a plateau. Then there is another rise and as soon as it reached at least over 100 degrees was then turned into a gas because it is the boiling point of water.
We can tell several things by looking at the graph. At point A we can assume the substance is a solid. The substance increases in temperature throughout the graph and it eventually turns into a gas by point E. At point B (55ºC) the substance turns into a liquid. Water's melting point is 0º C so we know this is not water. At this point, there is a plateau. This occurs because the substance is going through a phase change, and while this happens it does not change temperature. The substance continues to increase in temperature and once it has begun to boil it will become a gas through vaporization.
The graph starts at 30°C and rises in a straight line to 55°C, taking 41 minutes to reach 55°C. For another 41 minutes, the graph stays at 55°C. Then it rises again in a straight line for 39 minutes to 90°C. Once again, the graph remains the same temperature for 39 minutes. After that, the graph rises one last time to 120°, in a straight line, taking about 40 minutes. This substance cannot be water for several reasons. First of all, water's boiling point is 100°C; the graph shows the substance heating up to 120°C, which water is incapable of doing. Secondly, the graph rises evenly, then plateaus evenly for the same amount of time, while water has an inconsistant curve upward, only plateauing once it hits its boiling point. This graph could not demonstrate the heating curve of water, but more likely another substance.
This graph shows the heating curve of a solid object, other than ice. You can tell it is not a graph of water because when the object reaches 100 degrees celcius it continues to increas in temperature adn it takes the substance over 180 minutes to get to 100 degrees celcius. At point A the substance is in the solid phase os matter at 30 degrees celcius. At points B and C the solid has changes into a liquid form and begins too heat up more rapidly. At point D the liquid begins to turn into a gas state and then continues onto point E were the change is complete and the gass begins too heat up more quikly.
In this graph at point A the substance is in liquid's solid form, ice. After this point the water reaches a plateau at point B which is about 55°C. The water is starting to melt a little now and it's temperature is leveled out between points B and C at 55°C. At point D the solid is now a liquid at 90°C. It is now repeating itself by staying at the same temperature because it is changing phases between points D and E. Although this time instead of changing into a liquid, the liquid is turning into a gas. Once the liquid is a gas the graph continues upward. The Heating Curve of Water graph demonstrates how a solid changes into a liquid and then its final change into a gas.
As shown by the heating curve on the graph, the substance is not water because water's boiling point is 100°C and would plateau around there. Point A represents the liquid at it's freezing point, in the solid state. Point B represents it's melting point. In between points B and C the heat energy is changing the solid into the liquid phase, which is why there is no temperature change. The rise in between points C and D displays the liquid being heated into a gas. Point D represents the boiling point and the temperature does not change because the substance is being changed from a liquid to a gas. The substance is done evaporating at point E. The process is over and the heat energy now rises. If the heat continued long enough, the substance would have completely evaporated.
The graph shown is the Heating Curve of Water. At point A, the ice is slowly melting at 30°C until it reaches 55°C (point B) where it reaches a plateau and undergoes a phase change. By point C the water begins to boil and turn from water into a gas.At point D the water is still turning into a gas and is boiling at 100 degrees C. Then, at point E the water has turned into a gas and continues to heat up.
The substance probably starts as a liquid and will be heated, until it turns into a gas. The temperature starts at 30°C and rises to 55°C, which is its first plateau. Then its next plateau is at 90°C. Then it rises to 120°C. 120°C is probably its boiling point, and since the temperature has reached over 100°C it has probably turned into a gas. At the end of the graph I assume that the gas has vaporized. Also, the plateaus signal is that a phase change is a occurring.
In the graph, I think that from point A to E ice is being heated into a lquid, and then into gas. From 30°C to 50°C, or point A to point B, the ice is slowely melting from being heated. Then starting at 50°C the ice goes through the phase of turning into a liquid, therefore the temperature does not change and a plateau is formed in the graph. That is until point C. Then from point C to D the temperature of the water rises from 55 to 90°C. Then starting at 90°C, from point D to E, the water goes through the phase of turning into a gas. This is called vaporization. Therefore the temperature doesn't change and another plateua is seen on the graph. When going through a phase, the temperature doesn't change because the kinetic energy doesn't change. Finally, from point E and on, the temerature will rise, and more and more gas will evaporate, and that is why there is an increase at the end of the graph
From point A to point B the substance is being heated. While at B it starts to change from a solid into a liquid so the temperature stays the same. Starting at point C and ending D the substance begins to be heating again but this time as a liquid. Finally at point D the substance began to vaporize so again the temperature will stay the same. Then from point E on, the substance is a gas being heated to its top temperature of 115°C. I don't think this substance is water because the boiling point of water is 100°C and this substance begins to vaporize at 90°C. This graph of the Heating Curve of a Substance shows the temperature while a substance is changing from a solid, to a liquid, to a gas.
This graph demonstrates the heating curve of a substance starting in a solid form, and ending in the gas form. Starting at 30 degrees celcius, or A, this substance is a solid. It heats up to 55 degrees celcius, B, and this is when the solid starts to melt into a liquid. From B to C, the solid is going through a phase change from a solid to a liquid. The temperature does not change because the energy from the heat is not being used to increase the kinetic energy, but rather break up the bonds between the atoms. At C, the substance has completely changed into a liquid. It heats up to 90 degrees celcius, which is this substances boiling point. Once again, this substance is going through a phase change from a liquid into a gas through the vaporization process. The temperature does not change for the same reason as I stated during the last phase change. At E, the substance is done vaporizing and is completely a gas. From here, it keeps on heating up to the temperature of 120 degrees celcius. One can tell that this substance is not water because if it were, its solid state would have to start at 0 or below degrees celcius. Also, its boiling point would be more around 100, instead of 90.
In the graph shown, letter A starts at 30 degrees celsius at 0 minutes. Then, at letter B, it is at 55 degrees celsius at 41 minutes. After that, at letter C, it is the same temp. at 81 minutes. Then, for liquid D, the substance rises to 90 degrees celsius at 123 minutes. Then it repeats the cycle shown for the change from B to C going from D to E at 160 minutes. By now, a pattern is shown. That pattern will probably continue through letter F and more. This graph shows the Heating Curve of Water. "A" being the ice at 30 degrees celsius, "B" being the ice changing into water mostly, "C" being the water has almost reached its boiling point and is transforming into vapor, "D" the water is at its boiling point and has completed its transformation to vapor. That is the graph.
This substace is at about 30°C, which is room temperature, and means this sbstace is probably in liquid form. After 41 minutes of heating, the temperature leveled out for another 41 minutes and then steadily continued that pattern until the Scientist stopped his data collection, and that temperature was still ascending but the chart ended with the end of line ending up at around 120°C. This subsace is probably not water because water's climb to boiling point is a line curving upwards and then leveling out at around 100°C, but in this case, the substace continued to rise in temperature and it is unknown if it finally leveled out, since the scientist stopped the data collection, even though the substance was still ascending(?) at around120°C, past the boiling point of water.
The substance portrayed in the graph is not water because when changing phases, represented by the plateaus, the substance does not change at water's melting point and boiling point. The substance is going from a liquid to a gas. At point A (30˚C) the solid form of the substance is being heated into a liquid. At point B (55˚C) The solid is changing phases into a liquid because the temperature does not change. At point C (rising from point B) The liquid is being heated into a gas. At point D (forming a plateau at point C's hight) the change from a liquid to a gas is taking place. And finally at point E (heating from a gas) the gas is being heated up again hopefully changing into plasma.
In this graph showing the heating curve of a substance, there are two phase changes. From B to C, the plateau on the graph shows that there was no temperature change for 41 minutes and a phase change occurred. As more heat was added from C to D, the substance reached another plateau from D to E and another phase change occurred at 90°C. In conclusion, this substance is not water because there was a phase change at 55°C and there was no phase change at 100°C. I also believe that the first phase change (B to C) was the substance melting from a solid to a liquid and the second phase change (D to E) was the substance vaporizing into a gas, as more energy was added.
The liquid in this graph is not water. If it was water, you could tell that at 100°C it would turn into a gas. This liquid reaches its plateau at around 55°C. After that it continues at 90°C and 120°C. At point E it has completly transformed into a gas.
The graph shows the heating curve of a substance. This substance is not water and there are many reasons why this is true. At point A, the substance is in a solid phase and starts to rise in temperature at 30 degrees C. At point B (about 55 degrees C), the substance had changed phases and reached a plateau. At point C, the temperature begins to rise again as a change in matter occurs. At point D (90 degrees C), the temperature plateaus again. At point E, the temperature starts going up again and a change in matter occurs. The substance in the graph cannot be water for many reasons. First, water’s freezing point is 0 degrees C, but this substance starts at a higher temperature (30 degrees C). Also, the graph the matter changes phase for much longer than it takes water to change phases. In addition to that, the substance keeps rising in temperature even after it reaches 100 degrees C (water’s boiling points). Whereas, once water reaches 100 degrees C it plateaus. These points prove that the substance is not water.
in the line graph there are steady increases and then plateaus the plateaus are phase changes maybe from solid to liquid to gas the plateaus happen because when the phase change occurs the energy goes into the phase change not temperature increase until the substance reaches the final state
What is happening in the graph shown is a substance is changing from a solid, to a liquid, to a gas. The substance starts at point A as a solid at about 30°C. It is then heated up to about 55°C. Once it reaches point B at 55°C, it begins the phase change from solid to liquid. Therefore, 55°C is the melting point of the substance. That is why a plateau begins at 55°C, becuase temperature does not change during a phase change. At point C, the substance has completed the phase change and is now a liquid that begins to heat up. The liquid continues to heat up until it reaches point D at about 90°C. Once the substance reaches point D at 90°C, it begins the phase change from liquid to gas. Therefore, 90°C is the bioling point of the substance. There is another plateu at 90°C because the substance is again experiencing a phase change, and a temperature change does not occur during a phase change. At point E, the substance has completed the phase change and is now a gas that begins to heat up. The substance is not water because this substance has a melting point of 55°C and a boiling point of 90°C. Water has a melting point of 0°C and a boiling point of 100°C. Therefore, the substance cannot be water.
In point A, the substance is a solid. It heats up to point B where it begins its liquid phase. It then remains at a constant temperature until it reaches point C. After that, it heats up and the line rises to point D becoming a gas. For a while it stays at a constant temperature until it reaches point E. Finally, it becomes even hotter and becomes less and less dense. This cannot be water because water starts to heat up slowly, then it speed up, and then it finally slows down in heating. This graph follows a much different pattern than the heating curve of water.
This graph shows the heating curve of a substance that starts as a solid, melts into a liquid, and vaporizes into a gaseous form. The substance is not water because the graph suggests that it is in a solid state at 30°C and increasing. At 30°C, water would be in a liquid state. At point A, the graph suggests that the substance is a solid. The temperature of the substance is 30°C and is rising. At point B, the graph suggests that the substance is beginning to undergo a phase change. Based on other observations, it is likely that this phase change is from solid to liquid. This also explains the plateau beginning at point B. The current temperature is 55°C and is remaining constant. At point C, the phase change is apparently over and the temperature begins to climb again. At this point, the graph suggests that the substance is a liquid. At point C, the temperature is 55°C and is rising. At point D, the graph suggests that the substance is beginning a second phase change. This phase change is most likely from liquid to gas. The plateau here is most likely caused by the phase change. The temperature here is 90°C and is not changing. At point E, the second phase change is complete. The plateau is over and the temperature of the substance is rising again. At this point, the substance will be in a gaseous state. The temperature here is 90°C and is rising.
The substance in the graph could be identified as water. At phase A or the starting point the temperature is 30 degrees Celsius. At 41 minutes into the start the temperature has raised at point B to 55 degrees. This means the ice is heating to the extent where a phase change will occur. From point B to 41 minutes later at 82 minutes C, the process of heating stops during the phase change. The phase change is happening because the ice heats to its melting point. Moving on from measure C to D another 41 minutes later at 123 minutes there is another temperature increase raising it to 90 degrees Celsius. While raising the temperature it is heating the substance for another phase change. From D to E at 160 minutes into the experiment there is another phase change going from a liquid to a vapor. As the gas is getting heated it is getting ready to be changed to a plasma.
The graph shows The Heating Curve of Water. From point "A" to point "B" the ice is melting and becoming water. From point "B" to point "C" there is a plateau. Next the temperature begins rising again at about 55 degrees Celsius, from point "C" to point "D" the water is beginning to bubble but it is not quite vaporizing yet. Between point "D" and point "E" the water is starting to vaporize. After point "E" the water is vaporizing.
This graph is displaying a solid being boiled. This solid could not be water because the substance does not melt until 55° C, while ice melts at 0° C. At point A, the substance is a solid. From point A to B the solid is being heated. At point B, the substance is still a solid. From Point B to C, the solid is going through a phase change. The substance is changing from a solid to a liquid. At point C, the substance is a liquid. From point C to D, the liquid is being heated. At point D, the substance is still a liquid. From point D to E, a phase change is occurring. The liquid is changing into a gas. At point E, the substance is a gas. Until the graph ends, the water vapor is heating.
This graph indicates that the substance is not water. At point A, the substance is at 30°C and at that point is a solid. It immediately begins to heat up and plateaus at 55°C, or point B, because it is undergoing a phase change and doesn't change in temperature. At point C, the process off becoming a liquid has fully completed and the substance's temperature starts to rise again. From point C to Point D, the substance heats up until it boils and becomes a gas from D to E. Again, the temperature doesn't rise or fall during the phase change because energy is used to change the phase of the substance rather than to heat it up. At point D, the substance becomes water vapor or steam. At point E, the steam continues to rise in temperature.
The graph most likely shows the heating of a solid, such as ice. It starts off at 30° C and is heated. Then, at point B the solid turns into a liquid at 55° C, which continues to point C. Then from point C the temperature still increases and by point D (90° C) the liquid has evaporation. Then at point E, the liquid has completely turned into a gas. From point E it continues to heat up past boiling point.
This graph represents the heating curve of water. The temperature is getting hotter which causes the ice to start melting. At around 55 °C the ice changes to water and begins to form a plateau. Then the temperature rises to 95 °C and then goes all the way up to 115 °C. By now, it is most likely that the gas will begin the bioling point of water, since the boiling point is 100°C. When it reaches the boiling point of water, it is it starts to evaporate into a gas. The plateaus were slowly happenning when the water was chaning and no temperature change occurred during the temperature change during any of the plateaus. The ice was melting into water at first, but when the water was warming from water to boiling water which was 100°C. At the final plateau, the water slowey turned to water vapor. The heat had increased and if the experiment went even longer, there would have been no water in the beaker, since it all turned to water vapor and evaporated.
The substance represented on the heating curve is not water. At point A on the graph the substance is a solid and begins to immediately increase in temperature. When the substance heats to about 55°C, it begins to change into a liquid. This process takes approximately 41 minutes, which is point C. Then the substance that is now liquid begins to heat up to about 90°C. At point D the liquid begins a phase change and begins to change into a gas. This process is completed at 160 minutes, which is point E. Past point E, the substance in gas form heats up. The graph makes a plateau when phase changes occur because all of the heat energy is being used to change the substance instead of increasing the temperature of the substance. The reason why this substance is not water is because water's boiling point is 100°C and the graph shows that the boiling point is not 100°C.
The graph shows the heating curve of a substance that when heated, from letter A to B goes up by 25°C. Then, from the letters B to C, the temperature increase by 0°C. Then the process repeats itself. Also, the process repeats itself after the 120°C mark. That graph is not the heating curve of water, because water's heating curve has a steep increase in temperature from the beginning of the experiment to the first five minutes. Then, the heating curve plateaus at approximately 100°C. That is not at all like the graph shown.
This graph is demonstrating the Heating Curve of Water. At point A, the ice is at 30° C. Then at B the ice is warming at 55° C. After B the graph plateaus until point C because it is undergoing a phase change. Now the solid is becoming a liquid. From point C to point D the liquid is warming until it reaches 90°. From point D to E there is another plateau where the liquid goes through another phase change where the liquid vaporizes to a gas.
This graph is demonstrating the Heating Curve of Water. At point A, the ice is at 30° C. Then at B the ice is warming at 55° C. After B the graph plateaus until point C because it is undergoing a phase change. Now the solid is becoming a liquid. From point C to point D the liquid is warming until it reaches 90°. From point D to E there is another plateau where the liquid goes through another phase change where the liquid vaporizes to a gas.
The graph shows the that the water starts out frozen at approximately 30°C then rises steadily until it starts to pleataues at 55°C, showing that the ice is melting. Then it starts to rise again until it reaches 90°C then it pleataus again. Then it rises again until 120°C. What is happening in this graph is that it is clearly showing the water from its freezing point to its vaporization point.
The substance is in solid form between points A and B.The substance increases in temperature to 55°C.The substance goes through a phase change between points B and C. The substance changes from a solid into a liquid, therefore, the temperature remains at 55°C. The the substance increases in temperature from 55°C to 90°and it is still in liquid form. Between points D and E, the substance goes through a phase change by going from a liquiq into a gas.The temperature stays at 90°C. For the remainder of the experiment, from point to point E, the substance is in gas form, and it increases in temperature from 90°C to 120°C. The substance isn't water because the water's boiling point was 90°C, but water usually has a boiling point of 100°C.
The heating curve of the substance in the graph suggests that the substance is not water. The substance is at a solid state on point A on the graph. the solid starts at 30°C then immediatly heats up. he substance starts melting into a liquid at Point B (55°C). At point C (82 minutes). By point D (90°C), the liquid starts heating up again.At point E (160 minutes) the substance has completely changed into a gas.Each temperature plateau represents when the substance changes phases.
The Heating Curve of Water graph shows that point A is ice forming into a liquid, point B, at 55ºC, is mostly a liquid. By point C it is a liquid. At point D, the water starts to boil. After point E the water stays at a constant boiling point.
The substance is a solid substance between points A and B. The solid gets higher in temperature to 55°C.The substance goes through a phase change between points B and C. The substance changes from a solid into a liquid. The temperature stays at 55°C and it increases in temperature to 90°and it is still in liquid form. Between points D and E, the substance goes through a phase change by going from a liquid into a gas.The temperature stays at 90°C. For the remainder of the experiment, the substance is in gas form, and it goes up in temperature to 120°C. The reason why this substance is not water is because its boiling point is 90°C, although the regular boiling point of water is 100°C.
The example given describes a liquid getting turned into a gas. The graph shows that it goes up and then down a little the same way about 3 times. it becomes water the evaporates into gas.
In this graph it shows how the temperature rise while the substance goes into a change of state. this face a change of state of sublimation which means that when it plateaus at each point the heat breaks the bond between its molecules and making it the substance turning into gas. this substance is not water because it plateaus a lot when it goes into a change of state.
At first A is at a liquid state of matter. And is being warmed up to B which goes through a phase change to become a at a gas state. At B 55°C the temperature stays the same until C 82 minutes which the temperature rises until D at 123 minutes when the temperature rises to 90°C in which another phase change occurs turning the state of matter into vapor at E in which the vapors temperatures keeps on rising until 120°C at 201 minutes when the container holding the liquid at first would then have no more liquid and would have all escaped because of evaporation.
The substance in this graph is most likely the heating curve of water. The substance starts out as a solid (ice). The solid immediately starts to heat up, causing the temperature to rise. At point B the solid begins to form into a liquid (water). At point C, the solid has completed the transformation to liquid. By point D, the water begins its transformation into a gas. At point E, the liquid is now completely a gas.Each plateau occurs because of the transformation of the different phases of matter. This happens because each time there is a phase change, the heat being used, is actually being used as energy for the phase transformation.

The graph shows the heating curve of water. Point A on the graph seems to be at a solid state. Then the solid is seen melting into a liquid at point B.This substance is not ice or water because the graph shows that the substance reached 100 degrees Celsius, water’s boiling point, and continued to increase. But if the substance were a gas it would have had plateaus because liquids turn into gas when they reach a boiling pint. From B to C there are many plateaus because when a substance is phase changing its temperature stays the same. That means the plateaus show the change in substance.
This substance is not water. This graph is showing that a substance (probably a solid) starts out at 30°C. It than melts to a liquid and stays at the same temperature (55°C) until it starts to rise again and boil. when boiling, the temperature remains the same until it evaporates to a gas and than remains at 90°C. than it would heat up more and eventually there would be no more of this substance visible because it would have turned into a gas. This liquid is not water because water boils at 100°C and this graph says that the temperature was continuing to rise when it reached that temp, saying that it was not continually boiling but it was boiling at 90°C.
In the graph a substance is being heated. It starts at point "A" which is at 30°C which means that the substance being heated is still possibly ice at point "A". At point "B", 41 minutes into the heating experiment, the substance is at 55°C. At this point the substance has probably melted into water. Point "C", 82 minutes into the experiment is equal with point "B", at 55°C meaning that the substance has settled for a short period meaning that its characterizations have been completely changed into a liquid. About 120 minutes into the experiment point "D" is at 90°C The water now will have started to turn into a gas. At point "E" 160 minutes into the experiment the water has turned to a gas completely. The experiment continues for about 41 more minutes and reaches a temperature of 120°C by now the substance has evaporated and is just a boiling hot gas cloud. The substance can be water because in the experiment it shows all of the phases in which an ice cube can turn into a gas in the experiment.
The substance in the gaph starts as a liquid then probably ends up as a gas. at A the substane warms up to 30 degrees (C). At point B the substance warms up to 55 degrees. The substance is heating up and becoming a gas
This graph shows the heating curve of water. First the ice started to heat up until it reached that melting point at point B. During the phase change the substance did not gain heat and at Point C when the ice has completely turned into water and and has started to gain heat again. At pojnt D the water had started to vaporize into water vapor and has stopped gaining heat because it is in a phase change.
The substance starts at 30°c than it raises to 55°c. This substance is a solid because of the heating process the temperature rose. Between B and C it became a plateau. This is called a phase change. It started out as a solid and became a liquid at 55°c. From C to D the heat rises its still a liquid and it rises from 55°c to 90°c. At 90°c a phase change started and its changing to a gas because it boils. At point E the substance is completely a gas. The gas continues to rise from 90°c to 120°c.
From analyzing the graph, and noticing at which temperatures there are plateaus, I believe that the substance being heated is not water. It begins to be heated at a temperature of 30 degrees celsius, then the substance continues to heat at a rate which could easily be a rate water heats at, except, when the substance has been heated for 41 minutes, and reaches 50 degrees celsius its temperature stops rising for a period of 41 minutes. These "plateaus", as they are called on graphs, indicates that their is a phase change going on in the substance, because during a phase change, the heat usually used to heat the substance goes to breaking the molecular bonds of a substance. I am inclined to believe that this first plateau signifies the melting of the substance, because there are two plateaus on the graph and most substances only go through two phase changes if they are heated. They always melt at the lower temperature of the two. At 55 degrees celsius, water has no such change. At 0 degrees celsius water freezes, and at 100 degrees celsius, water boils. After the plateau, which ended after 82 minutes of heating, the temperature of the substance begins to rise a tad bit more quickly than before the phase change, and in a period of 39 minutes the substance's temperature rises 35 degrees celsius, and ceases to rise, and for another 39 minutes the substance goes through a phase change. at this phase change I believe that the substance is beginning to evaporate, because the phase change that happens at hotter temperature, usually is the turning of the substance from a liquid to a gas. After this plateau, the substance is continued to be heated until the time for the data collection has run out.
The substance that is being heated starts of as a liquid. when it rises from 30°C to 55°C it reaches its first plateau. The substance continues on its plateau a few minutes. It then starts to rise from 55°C to 90°C. The substance is now close to its boiling point. Finally the substance goes to its final point of 120° C. Through the graph the substance went from a liquid to a gas through evaporation. The plateaus were created because that is where the water slowly begins changing phases. At 55°C is the first point when it shows signs of it being boiled. At 90°C is the last stage before the substance gets boiled. The substance began to evaporate between 55°C and 90°C. At the end of the 201 minutes there would be a significant less amount of water in the beaker because most of it had been evaporated into a gas.
First, between points A and B there is a rise in temperature that causes the change of phases from a solid to a liquid at points B to D. The warmer temperature causes the substance to melt. Then the temperature increases from C to D and another phase change takes place from a liquid to a gas during the time between point D and E. This graph shows that the substance is not water because the substance changes from a liquid to a gas at about 90°C. Water's boiling point is 100°C, not 90°C, which is when this substance reached the point where it evaporated.
The ice gradually gets warmer in phase a-b. during phase b-c, the water is staying the same temperature because the temperature does not rise during a phase change. then the water is getting hotter in phase c-d. in phase d-e, the water becomes gaseous, forming another plateau.
The ice gradually gets warmer in phase a-b. during phase b-c, the water is staying the same temperature because the temperature does not rise during a phase change. then the water is getting hotter in phase c-d. in phase d-e, the water becomes gaseous, forming another plateau.
AT point A, substance is a solid. While rising and heating to point B, and solid is heating but not turning into a liquid quite yet. The first plateau is where the solid actually goes through a phase change and becomes a liquid. This phase change stops at point C. From point C to D, the liquid is heating up. AT point D is where the second phase change occurs. This is where the liquid turns into a gas. Once again, this phase change ends at point E. Then from point E on, the gas is heating/ turning into water vapor. By the end of the experiment, There would be none of the substance left in the beaker or whatever container the scientist used. This graph does portray the heating curve of water, not any other substance.
this is annoying
i love you
This graph shows the heating curve of a substance unknown to us. At point B the substance begins changing into a liquid. This can be determined because a plateau is formed at the phase change. At point C the substance is completely changed because the plateau ends, and the graph resumes its rise. At point D the liquid begins to change into a gas, again signified by a plateau. At point E the phase change is over, signified by the end of the plateau and the resuming of the increase in temperature.
