3. Liquefied air (assuming it is only O2 and N2) is kept in a container where pressure and temperature can be controlled.
a. What is the maximum temperature at which the mixture exists as a liquid? If this temperature is kept constant, what is the minimum pressure to keep the air in the liquid phase?
b. Because of a sudden drop in pressure to 2 bar, all the liquid evaporates. Calculate the volume of one mole of this vapor at -100oC.
