Did you know?
The
phase rule, first announced by J. Willard Gibbs in 1876, relates the
physical state of a mixture to the number of constituents in the system and to its conditions. When pressure
and temperature are the state variables, the rule can be written as follows:
f = c - p + 2
where
f is the number of independent variables that can be changed without changing the number of phases
present (called
degrees of freedom),
c is the
number of components, and
p is the number of stable phases. In binary phase diagrams, components are
the two materials plotted on the horizontal axis (e.g., silver and copper in the diagram shown).
