- does it compare with the known melting and boiling point? (1) 9. The average kinetic energy of water molecules is a measure of the temperature of water. When the temperature of water remains constant the average kinetic energy of the molecules remains constant, even though the water is being heated by the Bunsen flame. So, energy is being taken in by the water, but it is not being used to increase the kinetic energy of the molecules. 9.1 What type of energy are the water molecules gaining during a phase change?
