Heat of Vaporization?

Heat of vaporization is the amount of heat needed to convert a solid mass into a liquid without changing the temperature of the substance. Heat of vaporization differs for each substance. The heat of vaporization of water is 2260 Joules/g.
heat of vaporization - Definition
(n.) The heat absorbed per unit mass of a given material at its boiling point that completely converts the material to a gas at the same temperature: equal to the heat of condensation
