       11. A) Water changes to steam at a temperature of 100oC. If we keep adding
heat to a quantity of water at 100oC, it continues to boil with the conversion of liquid
to gas, but the temperature remains constant.
           B) On a molecular level, when a substance goes from a liquid to a gas,
works must be done to break the molecular bonds and to separate the molecules. The
heat energy must go into the work of separating the molecules and not into increasing
the molecular kinetic energy, which would increase the temperature. The heat associ-
ated with a phase change is called latent heat (latent means hidden).
