Q. 11.22 Answer the following questions based on the P – T phase diagram of :
(d) is heated to a temperature and compressed isothermally. What changes in its properties do you expect to observe?
70 oC is above the critical temperature of CO2. Once CO2 is isothermally compressed at this temperature it would not liquefy irrespective of how high the pressure is but at very high pressures CO2 will not behave as an ideal gas.
