Phase Diagrams (Section)

Referring to Figure describe the phase changes (and the temperatures at which they occur) when CO2 is heated from-80 to-20 °C at

Figure Phase diagram of co2. Note that a linear scale is used to represent temperature and a logarithmic scale to represent pressure.

(a) a constant pressure of 3 atm, (b) a constant pressure of 6 atm.
