As moist air is lifted and cooled, water vapor eventually condenses, which then allows for huge amounts of latent heat energy to be released, feeding the storm. 1  Condensation is a warming process. 2  Latent heat of fusion describes both changing from solid to liquid and from liquid to solid.
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!
