Question

wer the following:
For any substance, why does the temperature remain
constant during the change of state?
​

Answer 1

Explanation:

Heat is required to change the phase as well as to increase the temperature.

So, the temperature remains constant during the change of state.

Answer 2

Answer:

Because the temperature is used up for the conversion of change of state
