States of matter

Phase is a collection of state of a macroscopic physical system that is relatively serbasama both their chemical composition and properties of physical properties (eg density, crystal structure, index of refraction, and so forth). Examples of phases that we know is a solid, liquid, and gas. Less familiar phases include plasmas, Bose-Einstein condensation, and condensation Fermions. State phase of the magnetic material is paramagnetic and ferromagnetic.
