Examine the phase diagram for iodine shown in Figure 12.39(a).

What state transitions occur as we uniformly increase the pressure on a gaseous sample of iodine from 0.010 atm at 185 °C to 100 atm at 185 °C? Make a graph, analogous to the heating curve for water shown in Figure 12.36. Plot pressure versus time during the pressure increase.
