'''Condensation''' is    the change of the [[state of matter]] from the [[gas|gas phase]] into the [[liquid|liquid phase]], and is the reverse of [[vaporization]]. The word most often refers to the [[water cycle]].<ref name=Gold>{{GoldBookRef|title=condensation ''in atmospheric chemistry''|file=C01235}}</ref> It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or [[cloud condensation nuclei]] within the [[Earth's atmosphere|atmosphere]]. When the transition happens from the gaseous phase into the solid phase directly, the change is called [[Deposition (phase transition)|deposition]]. Condensation is usually associated with water.
