See below.


Vaporization is the phase transition of a substance from liquid to vapor.

Evaporation is a type of vaporization that occurs at the surface of a liquid at temperatures below the boiling temperature.

Boiling is the other type of vaporization: a rapid vaporization of liquid occurring at the liquid's boiling point (rather than below).

They are essentially the same.


"Evaporation" is commonly used to refer to the vaporization of a compound into ambient air. It may also refer to other systems, including partial vacuums.

"Vaporization" may be the better general term, as it refers to any phase change from liquid to gas, whether at ambient conditions or not.
