Question

) How does the average kinetic energy and the average potential energy of
molecules of a substance change during its change in phase at a constant
temperature, on heating?​

Answer 1

Explanation:

Average kinetic energy does not change. ... Explanation: When a substance is heated at constant temperature (i.e. during its phase change state), the heat supplied makes the vibrating molecules gain potential energy to overcome the intermolecular force of attraction and move about freely
