Heat of Vaporization
What is it?
Heat of Vaporization is the change in enthalpy (or heat) needed to cause the evaporation one mole of a liquid.
Give me an example!
When a substance reaches its heat of vaporization, the bonds between the molecules that hold it together in a liquid state break down and it becomes a gas. You might say the bonds between the molecules vaporize when the substance reaches its heat of vaporization.
