# The critical temperature (Tc) and critical pressure (Pc) of CO2 are 30.98°C and 73 atm respectively. Can CO2(g) be liquefied at 32°C and 80 atm pressure ?

CO2 gas cannot be liquefied at 32°C by applying a pressure of 80 atm. This is because the temperature is higher than critical temperature of CO2
