Question

Why does temperature remain constant during change of state of matter?​

Answer 1

Answer:

Heat is required to change the phase as well as to increase the temperature. During phase transitions, the heat supplied (called the latent heat) is fully utilised to change the state by overcoming the force of attraction between the particles.

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

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. It is due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant. Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed.
