A closed, rigid container with a volume of 1 m3 contains H2O initially at a pressure of 800 kPa and temperature of 500 C. Heat transfer occurs to the surroundings. At what temperature, in deg C, will condensation start to occur? As cooling continues, what percentage of the total mass will be condensed when the pressure reaches 175 kPa? At that point, what is the volume, in m3, of the liquid water?
