Phase Diagram for CO2The phase diagram for CO2 is shown in Figure 17-38 . (a) What is the phase of CO2 at T=20°C and P=500 kPa? (b) What is the phase of CO2 at T=−80°C 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 20 °C.
