A phase is a part of a system with uniform composition.
In physics and chemistry , a phase in a physically distinctive form of matter , such as solid , liquid , gas or plasma.
A phase matter is characterised by having relatively uniform chemical and physical properities . Phases are different from states of matter.
The states of matter (e.g ., solid , liquid , gas ) are phases but matter can exist in different phases and yet be in the same type of matter. For example , liquid mixtures can exist in multiple phases such as oily and aqueous phase.
some different types of phases are : solid, liquid,gas , plasma etc.
The term phase can also sometime mean describe equilibrium in phase diagram
