WebFeb 16, 2024 · The Gibbs Phase rule can be applied to a P-T thermodynamic diagrams for pure substances. On any such of diagram, each point represents a state of the material. Once the point has been located, all other thermodynamic properties can be read off. In thermodynamics, the phase rule is a general principle governing "pVT" systems, whose thermodynamic states are completely described by the variables pressure (p), volume (V) and temperature (T), in thermodynamic equilibrium. If F is the number of degrees of freedom, C is the number of components and P is the number of phases, then It was derived by American physicist Josiah Willard Gibbs in his landmark paper titled On the Equ…
