Summary
The
Phase Rule
, formulated by
Josiah Willard Gibbs

Degrees Of Freedom
in a
Closed System
at equilibrium based on the
Number of phases
, components, and
External Variables
. It is expressed as F = C - P + 2, where F is the
Degrees Of Freedom
, C is the
Number of components
, and P is the
Number of phases
present.
