Question

Why does the temperature not rise during change of state of matter?

Answer 1

The heat is used to break the bonds between the ice molecules as they turn into a liquid phase. Since the average kinetic energy of the molecules does not change at the moment of melting, the temperature of the molecules does not change.

Answer 2

Answer:

HERE IS YOUR ANS MATE

To change state you need to overcome forces between the particles in the substance, and this needs energy. This is why when you heat the substance up atthis point you don't see an increase in temperature. It's called latent heat because it is 'hidden'.
