Phase rule (Physics Chem.) A generalization with regard to systems of chemical equilibrium, discovered by Prof. J. Willard Gibbs.

Thus, if the components be salt and water, and the phases salt, ice, saturated solution, and vapor, the system is invariant, that is, there is only one set of conditions under which these four phases can exist in equilibrium. If only three phases be considered, the system is univariant, that is, the fixing of one condition, as temperature, determines the others.
