A phase transition is a natural physical process. It has the characteristic of taking a given medium with given properties and transforming some or all of that medium, into a new medium with new properties. Phase transitions occur frequently and are found everywhere in the natural world. Some engineering techniques exploit certain types of phase transition.
In thermodynamics, a phase transition is the transformation of a thermodynamic system from one phase to another.
At a phase transition point, physical properties may undergo abrupt change: for instance, the volume of the two phases may be vastly different as is illustrated by the boiling of liquid water to form steam.
The term is most commonly used to describe transitions between solid, liquid and gaseous states of matter, in rare cases including plasma.
