1. The normal melting point ofcyclohexane is 7.0°C. The 3 phases of cyclohexane co-existin dynamic equilibrium at 24.0 torr and 3.8°C. At287.0°C gaseous cyclohexane can be compressed to a liquid undera pressure of 49.3 atm. Above this temperature, cyclohexane cannot be compressed under any pressure.
a. Sketch a phase diagram for cyclohexane
b. What is the state of cyclohexane at 50.0°C and 3.0 atm
c. What phase change occurs when cyclohexane undergoes isobaric cooling at 3.0 atm from50.0°C to 7.0°C.
