MathLiveGibbs phase rule
Gives the number of independent intensive variables (degrees of freedom) that can be varied without changing the number of phases in a system at equilibrium. It is used to analyse how many conditions such as temperature or pressure can be set independently in a multicomponent, multiphase system.
F = C - P + 2What the symbols mean
| degrees of freedom (number of independent intensive variables) | |
| number of components in the system | |
| number of phases present at equilibrium |
