<P> The term phase transition ( or phase change ) is most commonly used to describe transitions between solid , liquid and gaseous states of matter , and , in rare cases , plasma ( physics ) . A phase of a thermodynamic system and the states of matter have uniform 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 some external condition , 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 are common in nature and used today in many technologies . </P>
