Air (consisting of O2 and N2) is cooled to 80 K and a total pressure of 1 atm, at which point a part of it is liquefies. Calculate the composition of the liquid and gas phases under these conditions, assuming that Raoult's Law (ideal liquid phase) holds and also that the gas phase is also ideal. Data: At 80 K, the saturated vapor pressures of N2 and O2 are respectively p*N2=1.341 atm and p*O2= 0.297 atm. Caution: Due to partial liquefaction, the ratio 21:79 (O2:N2) is not valid for the composition of air at 80 K
