phase of matter
subject			fact

phase of matter	has definition When used in reference to matter, describes its possible states: solid phase, liquid phase, gas phase. More generally, refers to the possible descriptions of a physical system as features on which it depends (temperature, string coupling constant values, form of spacetime, etc.) are varied.
	is a kind of collection of particles
physical object	has location or center of gravity
	has angular momentum
	has mass
	has velocity
	has momentum
	has temperature
	has volume
	has extent
	has material

Kinds of phase of matter :

• gas (5 kinds, 21 facts) - A phase of matter consisting of a low density collection of particles which have no short range order, The gaseous component of a galaxy, includes nebula
• liquid (2 kinds, 6 facts) - a high density cohesive collection of particle which move relative to one another and which has short range order
• solid (46 kinds, 358 facts) - a high density collection of particle which do not move relative to one another (except for thermal oscillations)
• ylem (3 facts) - The word used by Gamow and his collaborators for the primordial material of the Big Bang. In most of his work Gamow assumed that the ylem consisted entirely of neutrons. In inflationary cosmology, the role of the ylem is played by the false vacuum., Primordial state of matter - neutrons and their decay products (protons and electrons) - before the Big Bang. The term was taken from Aristotle and used for the α-β-γ theory.
