When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing.

At what temperature C and K are the same?
Both cannot be same.. Bcoz, *c and K scale have arithmetic relation... so it cant be same..
When a solid melts its temperature remains constant So where does the heat energy go?
Temperature indicate kinetic energy density in molecular vibration. Over phase change, energy go to motion and fight against molecular interaction make it mobile.Liquid is more mobile in compare to solidVapour is more mobile in compare to liquid.Molecular vibration (temperature) stay the same while the energy input go to mobility (latent heat).Read more: When_a_solid_melts_its_temperature_remains_same_so_where_does_the_temperature_goes
What is the same as the melting point of mercury?
The freezing point of salt is also its freezing point. This is the case with any substance, as it is the temperature that an element changes from the solid to liquid phase or the liquid to solid phase.
A gas is most likely to change to the liquid phase when the pressure on the gas?
A gas is most likely to change to the liquid phase when the pressure on the gas is increased. This is because the same number of molecules will have less space to occupy.
Do air pressure and temperature change in the same way with altitude?
yep
What happens to a substances temperature during a phase change?
stays the same
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
Could a phase graph with little temperature increase and a lot of heat be the same as latent heat?
Yes. Strictly speaking there should be no temperature change during a phase change.
Can molecules change phase and increase temperature at the same time?
Yes, it is possible.
Which stays the same when a substance switches from liquid to gas?
During the phase change, the temperature stays the same.
Sometimes heat energy is added but the temperature stays the same when is this?
During a phase change.
What happens when heat is added to a system?
When heat is added to a system, the temperature increases, unless there is a phase change taking place. In that case, temperature remains the same, and the only observable difference is the phase change.
What rule can you state about the relationship between phase changes and temperature?
As the temperature increases, the phases change from having the slowest amount of molecules to having the fastest amount of molecules (solid-liquid-gas)
Which phase change temperatures are identical on the phase diagram?
The temperature for melting and freezing is the same. The temperature for vaporization (boiling) and condensation is also identical. Refer to the related link for a diagram that illustrates phase changes.
What happens to temperature when energy is added as heat?
Either the temperature will increase, or it will remain the same. In the latter case, there is a phase change, as when ice melts.
What phase change mean?
changes from one state to another without a change in chemical composition
When heat flows from a hot object to a cold object the temperature of the cold object increases while the temperature of the hot object is what?
The temperature of the hot object will be reduced unless it is undergoing a phase change - in which case it may remain at the same temperature until the phase change is complete - and then drop in temperature if the cold object has not reached the same temperature.
