100 moles of water at 70 degrees celsius is brought into thermal contact with 100 moles of a monatomic gas at 20 degrees celsius, and the two substances exchange heat until they reach the same temperature. Assuming that no heat is lost to the surroundings, there is no volume change, and that the heat capacity of liquid water is Cv=Cp=75.2 J/mole-K. What is the equilibrium temperature of the water/gas system? How much heat is exchanged between the gas and the water? What is the change in the total internal energy of the water/gas system? What is the change in the total enthalpy of the water/gas system?
