Within what range can you restrict the values of P and/or T if the following information is known about sulfur? Use Figure 8.11 to answer this problem.

a. Only the rhombic solid phase is observed for P = 1atm.

b. When the pressure on the vapor is increased, the monoclinic solid phase is formed.

c. Solid, liquid, and gas phases coexist at equilibrium.

d. As the temperature is increased, the rhombic solid phase is converted to the monoclinic solid phase.

e. As the temperature is increased at 1 atm, the rhombic solid phase is converted to the liquid directly.
