The temperature remains constant during the phase change until all of the substance has been changed or converted into the new phase (i.e. solid to liquid). That is because all of the energy going into (being absorbed by) the substance is being applied toward converting the substance into the new phase. At the point that the last entity of the substance has been converted into the new phase and no more of the old phase (solid) remains, the energy absorbed will begin to raise the temperature of the substance.

What is unique about temperature during phase changes?
It doesn't change notwithstanding heat energy changes.
What happens to temperature during a phase change?
Temperature is constant during a phase change.
What do you think will happen to the temperature of a substance during a phase change?
Typically, the temperature doesn't change during a phase change.
Does the temperature of a substance change before the change of state is complete?
No. During a phase change the temperature is constant until the phase change is complete.
How do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
Why doesn't the temperature change fast during a phase change?
Basically because there is energy needed for the temperature to rise or become lower, but energy is also needed to change the phase, so instead of the energy being used to change the temperature, it is being used to change the phase, therefore temperature does not change.
What A steep slope on a phase-change graph indicates?
Different
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.
Why does phase change occur in materials?
Changing the temperature or pressure of a material we can change the phase.
What happens to a substances temperature during a phase change?
stays the same
What causes a substance to change a phase?
change in temperature
