25.00 g of steam at 373 K is added to 390 g H2O(l) at 298 K at constant pressure of 1 bar. Is the final state of the system steam or water? Calculate (delta)S for the process. Assume that the final state is liquid water. If this is not the case, the calculated temperature will be greater than 373 K.

If we have water vapor at 100 oC and 1.2 atm we
should expect it to condense into liquid water as this is the most
stable phase under those conditions (i.e. the boiling point of
water should be higher than 100 oC at 1.2 atm ). This,
in turn, should mean that the chemical potential of the water vapor
should be larger than that of the liquid under those conditions.
