LECTURE 5: PHASE EQUILIBRIA

LECTURE 5: PHASE EQUILIBRIA. PHASE EQUILIBRIA. Phase equilibrium describes the way phases (such as solid, liquid and/or gas) co-exist at some temperatures and pressure, but interchange at others. Energetic introduction to phase equilibria. Why does an ice cube melt in the mouth?.

PHASE EQUILIBRIA AND THE PHASE RULE

PHASE EQUILIBRIA AND THE PHASE RULE. F = C - P + 2. The three primary phases of matter are often defined individually under different conditions. In practice we encounter states of matter in coexistence.
