Water in a closed, rigid, 0.085 m3 (85 L) tank exists at 5 bar (500 kPa) and 280 C. The water is cooled by heat transfer to the surroundings until its temperature reaches 20 C. Calculate the following quantities:a. the pressure at the end of the process, in kPa. b. the mas of liquid water in the container at the end of the process, in kg. c. the mass of the water vapor in the container at the end of the process, in kg. d. the heat transfer, in kJ, from the water during the process.
