Gasses cannot be liquified above critical temperature but at high pressure they can be.

Q. Critical temperature of $C O_{2}$ is $31. 2^{\circ} C$ . In summer, the room temperature is $4 0^{\circ} C$

$C O_{2}$ cannot be liquefied

can be liquefied with increase of pressure

can be liquefied with decrease of pressure

can be liquefied if temperature of $C O_{2}$ is decreased below $31. 2^{\circ} C$

Gasses cannot be liquified above critical temperature but at high pressure they can be.

Q. Critical temperature of CO2​ is 31.2∘C . In summer, the room temperature is 40∘C

CO2​ cannot be liquefied

can be liquefied with increase of pressure

can be liquefied with decrease of pressure

can be liquefied if temperature of CO2​ is decreased below 31.2∘C
