A substance on heating undergoes (i) a rise in its temperature, (ii) A change in its phase without change in its temperature. In each case, state the change in energy of molecules of the substance.

Solution:

(i) The average kinetic energy of molecules increases with the increase in temperature.

(ii) Average potential energy of molecules increases with a change in its phase.
