A generalization in the study of equilibriums between two or more phases of a system, stating that the number of degrees of freedom is equal to the number of components minus the number of phases plus the constant 2, or F = C − P + 2
A rule used in thermodynamics stating that the number of degrees of freedom in a physical system at equilibrium is equal to the number of chemical components in the system minus the number of phases plus the constant 2.
(physics) The rule which states that the number of degrees of freedom in a system at equilibrium equals the number of components minus the number of phases plus 2
Phase-rule Sentence Examples
The Phase Rule of Willard Gibbs, especially as developed by Bakhuis Roozeboom, is a most useful guide in such investigations.
The general theory of such equilibria will be studied later under the head of the phase rule.
The phase rule combined with the latent heat equation contains the whole theory of chemical and physical equilibrium.
For the quantitative study of such systems in detail it is convenient to draw plane diagrams which are theoretically projections of the curves of the solid phase rule diagram on one or other of these planes.
