2PhaseA chemically and structurally homogeneous region of a materialA part of a system, physically distinct, macroscopically homogeneous, and of fixed or variable composition. It is mechanically separable from the rest of the system. That is, aIt is mechanically separable from the rest of the system. That is, a phase is a region within which all the intensive variables vary continuously, whereas at least some of them have discontinuities at the borders between phases.ice waterice + waterÆ2 phases = solid phase + liquid phase2 phases solid phase liquid phaseI want to drink “2-phase system consisting of solid water and liquid water”.
