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?
