Physics · Thermodynamics
In a multiphase system, according to Gibbs' phase rule, how can the degrees of freedom (F) be determined using the number of phases (π) and the number of chemical species (N) when only temperature and pressure are the influential intensive variables?
- 1F = 2 - π + N✓
- 2F = 2 + π - N
- 3F = 2 - π - N
- 4F = 2 + π + N
Correct answer
F = 2 - π + N
