Thermodynamic Phase

Part of a thermodynamic system having uniform properties (e.g., density, crystal structure, index of refraction). The most familiar examples of phases are solids (minerals), liquids, and gases. Less familiar phases include plasmas, quark-gluon plasmas, Bose-Einstein condensates and fermionic condensates, strange matter, liquid crystals, superfluids and supersolids.
