A phase diagram for CO2 is shown in the figure shown a) What is
the phase of CO2 at T = 2-C and P = 500 kPa? (b) What is the phase
of CO2 at T = -80C and P = 120 kPa? (c) For reasons of economy and
convenience, bulk CO2 is often transported in liquid form in
pressurized tanks. Using the phase diagram, determine the minimum
pressure required to keep CO2 in the liquid phase at 20C.

Among other things, phase diagrams help us predict those
conditions under which a substance will exist as a supercritical
fluid. Supercritical CO2 is especially useful as it is very
effective at dissolving nonpolar oils which constitute many of the
flavouring or odor-causing compounds in foods. For example, food
companies use supercritical CO2 to extract caffeine from
coffee.
a) Use the following data to label the following points on the
phase diagram for CO2: Triple point -57°C, 5.1 atm, Normal
sublimation...
