Chapter 8 Phase Diagrams - Western University
physics.uwo.caGibbs' phase rule describes the possible # of degrees of freedom (F) in a closed system at equilibrium, in terms of the number of separate phases (P) and the number of chemical components (C) in the system (derived from thermodynamic principles by Josiah W. Gibbs in the 1870s) Component is the minimum # of species necessary to define the

Phase transitions in the P − T phase diagram are described by the Gibbs enthalpy G(T,P,N), as defined by (5.11), which is itself a function of the pressure P and of the temperature T. G(T,P,N) changes continuously across the phase boundary when the transition is of first order. The entropy S and volume V, which are given by

Willard Gibbs in 1876, relates the physical state of a mixture to the number of constituents in the system and to its conditions. It was also Gibbs who first called each homogeneous region in a system by the term "phase." When pressure and temperature are the state variables, the rule can be
