The critical temperature (T_c) of any gasis defined as the value of temperature above which no gas can be liquefied, and the pressure at the critical temperature is calledcritical pressure (P_c).

So, as the CO₂ gas cannot be liquefied at temperature which is greater than its critical temperature i.e 30.98°C even by applying any pressure. So as the given temperature is 32°C by applying a pressure of 80atm the CO₂ gas cannot be liquefied.
