Ar expands adiabatically no heat in no heat out from t , Ask an Expert

Academics

Air expands adiabatically (no heat in, no heat out) from T = 300 K and P = 100 atm to a final pressure of 1 atm. Treat the gas as ideal with Cp/Cv = 1.4, and decide the final temperature. Compare your result to the boiling points of oxygen (90.2 K) and nitrogen (77.4 K). Could this method result in the liquefaction of air?
