H2O(l) and H2O(g) are in equilibrium in a constant-volume container at 300K and 0.0328 atm. The temperature of the sample is then reduced to 290K and Ar gas is added in such a way as to maintain the vapor pressure of the H2O at 0.0328 atm. Compute the partial pressure of Ar(g) that is needed to achieve this. You may assume that delta(vap)H for water is independent of temperature and pressure
