A piston-cylinder assembly contains 2.8 kg of water at 237.3°C and 3 bar. The water is compressed to a saturated vapor state where the pressure is 52 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 213 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water.
