A domestic water heater holds 189 L of water at 60 degrees C 1 atm. Determine the exergy of the hot water, in kJ. To what elevation, in m, would a 1000-kg mass have to be raised from zero elevation relative to the reference environment for its exergy to equal that of the hot water? Let Tsubzero = 298K, psubzero = 1 atm, and g = 9.81m/s^2
