The distinct forms in which matter can exist, described by its compressibility behaviour and structural rigidity.
The five most typical states of matter are:
The Liquid, Gas and Supercritical Fluid are combined under the term Fluid.
It is closely related to the concept of Phase which exists in one of the states of matter.
The process of changing the state from one to another is called Phase Transition.
