Use the accompanying phase diagram for sulfur to answer the following questions. (The phase diagram is not to scale.)

a. How many triple points are in the phase diagram?
b. What phases are in equilibrium at each of the triple points?
c. What phase is stable at room temperature and 1.0 atm pressure?
d. Can monoclinic sulfur exist in equilibrium with sulfur vapor?
e. What are the normal melting point and normal boiling point of sulfur?
f. Which is the denser solid phase, monoclinic or rhombic sulfur?
