For a system of two components present as two phases, with pressure not fixed, the degrees of freedom number

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

Answer: B

Substituting into the full rule gives 2 minus 2 plus 2, that is two. Temperature and one composition may be chosen independently, or temperature and pressure, but fixing any two of them settles the whole state of the system.
