Answer 2

Answer:

The temperature remains constant during the change of state because the heat energy which is supplied to change the state of matter is used in breaking the intermolecular forces and other attractive forces. ... Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed.
