Heat of vaporization — Science definition
The energy absorbed to boil a given amount of a liquid (and released when that amount condenses); larger than the heat of fusion.

In use
The energy needed to melt a sample is its heat of fusion; the (larger) energy needed to boil it is its heat of vaporization.
