Question:

Shown here is the phase diagram for compound X. The triple point of X is €“25.1°C at 0.50 atm and the critical point is 22°C and 21.3 atm.

a. What is the state of X at position A?
b. If we decrease the temperature from the compound at position A to €“28.2°C while holding the pressure constant, what is the state of X?
c. If we take the compound starting under the conditions of part b and increase the temperature to 15.3°C and decrease the pressure to 0.002 atm, what is the state of X?
d. Would it be possible to make the compound starting under the conditions of part c a solid by increasing just the pressure?
