A vaporization occurs when a liquid releases its molecules to the surroundings after absorbing some energy. The energy needed is called the heat of vaporization.

If the vapors are in equilibrium with the liquid, formed and returned in balance, the temperature at which it occurs is called the boiling point and the pressure needs to be noted. The boiling point is usually at 1 atm (760 mm Hg) pressure.

The same energy can be provided at lower temperature, takes longer to remove liquid and is not an equilibrium process: evaporation.

Water takes ~40-44 kJ/mole in ordinary circumstances, whether it’s cooking rice or letting a spill dry up.
