For a single component two phase mixture, the number of independent variable properties are_________________?
Correct answer: B. One
- A. Two
- B. One
- C. Zero
- D. Three
Explanation
For a one-component, two-phase system, Gibbs phase rule gives F = 1 - 2 + 2 = 1. One intensive property, such as temperature or pressure, can therefore be chosen independently, while the other is fixed by phase equilibrium.
