Gibbs' Phase Rule Calculator

How to Use This Calculator

Enter the number of components (C) and phases (P) in your system. The calculator will automatically compute the degrees of freedom (F) using Gibbs' Phase Rule formula.

What is this Calculator Used For?

This calculator helps chemists and chemical engineers determine the degrees of freedom in a system, which indicates how many variables (such as temperature, pressure, or composition) can be independently changed without altering the number of phases.

Formula

Gibbs' Phase Rule: F = C - P + 2

Example

If a system contains 2 components (C = 2) and 3 phases (P = 3):

F = 2 - 3 + 2 = 1. So, there is 1 degree of freedom.
