Gibbs' Phase Rule Calculator

Find degrees of freedom of a system.

Degrees of freedom (F) 1

Formula: F = C − P + 2

Step-by-step with your numbers:

1. Values used:

2. Components (C) = 1

3. Phases (P) = 2

5. Degrees of freedom (F) = 1

Did we solve your problem today?

The phase rule gives how many variables you can change independently.

The math behind it

F = C − P + 2, where C is the number of components and P the number of phases in equilibrium.

Water boiling (1 component, 2 phases) → F = 1.

Triple point?

1 component, 3 phases → F = 0 (a fixed point).
