for any substance, why does the temperature remain constant during the changes of state?

$\huge\bold\star\red{Answer}$

during the change of any state of matter heat is supplied to the substance. the molecules of this metal used to overcome to force of attraction between the particles, at this period of time, temperature remains constant. this extra heat is acquired by the molecules in the form of hidden heat called latent heat to change from one state of matter to the other state.

Answer 2

Answer:

Since the heat is used to overcome the force of attraction, the temperature of the substance does not change. The heat energy absorbed in this case is called as the latent heat. The temperature of the substance remains equal to the latent heat provided to or released by it. That's why for any substance, the temperature remain constant during the change of state.
