Heat - Explain that Stuff

Similarly, you need to supply heat to change a liquid into a gas, and this is called the latent heat of vaporization. Latent heat is a kind of energy and, although it may seem to be "hidden," it doesn't vanish into thin air. When liquid water freezes and turns back to ice, the latent heat of fusion is given off again.
