The critical temperature (Tc) and critical pressure (Pc) of CO2 are 30

1.	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? Give reason.
Answer» Given, Critical temperature (Tc) of CO₂ = 30.98˚C Critical pressure (Pc) of CO₂ = 73 atm As we know that a gas can not be liquefied above critical temperature and critical pressure. Hence, CO₂(g) can not be liquefied at 32˚C and 80 atm pressure.

Answer»

Given,

Critical temperature (Tc) of CO₂ = 30.98˚C

Critical pressure (Pc) of CO₂ = 73 atm

As we know that a gas can not be liquefied above critical temperature and critical pressure. Hence, CO₂(g) can not be liquefied at 32˚C and 80 atm pressure.
