Sulfur exhibits two solid phases, rhombic and monoclinic. 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 diagrams.
b) What phases are in equilibrium at each of the triple points.
c) What is the stable phase at 1 atm and 100 C°?
d) What are the normal melting point and normal boiling point of sulfur?
e) What is the densest phase?
f) At a pressure of 1.0 x 10-5, can rhombic sulfur sublime?
g) What phase changes occur when the pressure on the sample of sulfur at 100°C is increased from 1.0 x 10-8 atm to 1500 atm?
