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...

What does the triple point on a phase diagram represent? Select one: a. It represents the conditions under which a substance can exist in two of the three phases in stable form. b. It represents the point at which the distinction between liquid and gas phases becomes unclear. c. It represents the conditions of pressure and temperature under which solid, liquid, and gas all co-exist. d. It represents the point at which the substance undergoes sublimation.

CHEM 197B Supplemental Instruction Differentiating Characteristics: Phase Behavior Homework2 The inhalation anesthetics used in modern medicine are halogenated ethers, which are carbon- based compounds containing at least one C-O-C group and different halogen atoms (e.g., F, Ci). The vapor pressure curves for several of these substances are shown in the graph: 1600 1400 1200 Most medical vaporizers are kept at a constant temperature close to 20 °C and 1 atm (760 mm Hg).

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.
