Why does the temperature of a substance remain constant during change in state?

Explanation:
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.

ANSWER:
Latent heat
Heat is used up in changing the state by overcoming
the force of attraction between the particles.
Explanation:
The temperature remains constant as the heat gets used up in changing the state by overcoming the
forces of attraction between the particles.
For example, a solid melts on heating. Its temperature does not rise until the entire solid is converted
into liquid. This heat energy gets hidden into the contents and is known as the latent heat.
