Question

Why temperature does not change when any substance melts and cools?​

Answer 1

Answer:

As the ice melts, its temperature does not rise. All of the energy that is being put into the ice goes into the melting process and not into any increase in temperature. During the melting process, the two states – solid and liquid – are in equilibrium with one another.

Answer 2

As the ice melts, its temperature does not rise. All of the energy that is being put into the ice goes into the melting process and not into any increase in temperature. ... As with the previous state change, the temperature will remain at 100°C while the water molecules are going from the liquid to the gas or vapor state.
