Answer the following questions based on the P-T phase diagram of CO2:
CO2 at 1 atm pressure and temperature – 60°C is compressed isothermally. Does it go through a liquid phase?
What happens when CO2 at 4 atm pressure is cooled from room temperature at constant pressure?
Describe qualitatively the changes In a given mass of solid CO2 at 10 atm pressure and temperature -65°C as it is heated up to room temperature at constant pressure.
CO2 is heated to a temperature 700C and compressed isothermally. What changes in its properties do you expect to observe?
