The term '''phase transition''' (or '''phase change''') is most commonly used to describe transitions between [[solid]], [[liquid]], and [[gas]]eous [[states of matter]], as well as [[plasma (physics)|plasma]] in rare cases. A phase of a thermodynamic system and the states of matter have uniform [[physical property|physical properties]]. During a phase transition of a given medium, certain properties of the medium change, often discontinuously, as a result of the change of external conditions, such as [[temperature]], [[pressure]], or others. For example, a liquid may become gas upon heating to the [[boiling point]], resulting in an abrupt change in volume. The measurement of the external conditions at which the transformation occurs is termed the phase transition. Phase transitions commonly occur in nature and are used today in many technologies.
