A) Water, initially saturated vapor at 10.8 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored.
B) A piston-cylinder assembly contains 2 kg of water at 210.6^{o}C and 3 bar. The water is compressed to a saturated vapor state where the pressure is 50.7 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 252 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water.
