Chapter 4: Physical Transformations of Pure Substances PHASE DIAGRAMS 4.1 The stabilities of phases phase, a form of matter that is uniform throughout in chemical composition and physical state. phase transition, the spontaneous conversion of one phase into another phase. transition temperature, the temperature at which the two phases are in equilibrium . metastable phase, a thermodynamically unstable phase that persists because the transition is kinetically hindered.
