What is Vaporization?
[[File:77855181_bromine624.jpg|thumb|right|A [[laboratory flask]] filled with pure [[bromine]], a liquid that evaporates really fast]] '''Vaporization''' is a [[phase change]] from [[liquid]] to [[vapor]]. There are two types of vaporization: [[evaporation]] and [[boiling]]. Evaporation is a phase change from liquid to vapour. Evaporation happens below the [[boiling point]] of a substance at a given [[pressure]]. Evaporation happens on a surface. Boiling is also a phase change from liquid to [[gas]]. Boiling takes place when the [[vapor pressure]] of the [[substance]] is greater than or equal to the pressure of its environment. The temperature at which a substance boils is called the boiling point. {{Physics-stub}} {{States of matter}} [[Category:States of matter]]
