Along a two-phase curve of a one-component system the degrees of freedom number

  • A.two
  • B.zero
  • C.three
  • D.one

Answer: D

Correct answer: one

\[ F = 1 - 2 + 2 = 1. \] Fixing either temperature or pressure fixes the other, which is why two-phase equilibria appear as curves. The vapour pressure of a liquid is a function of temperature alone for precisely this reason.
