One-Component Phase Diagram Quiz The
phase diagram for sulfur is shown below

• a. Label the field where rhombic sulfur, S(rh),
  liquid sulfur, S(l), and sulfur vapor, S(g) are
  stable. The stability field for S(m) is already
  labeled.
• b. Label all two phase equilibria and note the
  identity of these phases.
• c. Label any triple points and indicate the
  phases that are in equilibrium at those points.
• d. Label the position of the critical point.
• Will either S(rh) or S(m) float on molten sulfur?
  
• No, the slopes of both equilibrium lines are
  positive.
