Condensation commonly occurs when a [[vapor]] is cooled and/or compressed to its [[saturation]] limit when the [[molecular]] [[density]] in the [[gas]] [[phase]] reaches its maximal [[threshold]]. Vapor cooling and compressing equipment that collects condensed liquids is called "condenser". | Condensation commonly occurs when a [[vapor]] is cooled and/or compressed to its [[saturation]] limit when the [[molecular]] [[density]] in the [[gas]] [[phase]] reaches its maximal [[threshold]].
