Heat of Vaporization-the amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature. For water at its normal boiling point of 100 C, the heat of vaporization is 2260 J g-1. 2260 J of heat must be absorbed by the water. Conversely, when 1 g of steam at 100 C condenses to give 1 g of water at 100 C, 2260 J of heat will be released to the surroundings.
The heat of vaporization is the energy required to change a liquid into a gas at its boiling point. Boiling requires energy, whereas condensation loses energy. Both the heat of fusion and the heat of vaporization are part of a formula. Now that you are armed with your heat of fusion and your heat of vaporization information, you are about to be one hot chemist - but not too hot, you don't want to vaporize!
