phase rule equation : F = C – P + 2 I) Phase (P) A phase is defined as “ an homogeneous, physically distinct and mechanically separable portion of system, which is separated from other such parts of the system by definite boundary surfaces” Example : 1. Liquid phase : The number of liquid phase depends on the number of
When water starts boiling, it undergoes a phase transition from a liquid to a gas phase. For both phases independently, the equation of state is a well-defined regular function, continuous, with continuous derivatives.
