A piston-cylinder device containing 10 kg of water is arranged to maintain a constant pressure of 800 kPA. The initial volume of this device is 3.843 m3. It is now cooled until the volume is 1.1 m3. 1) What is the initial (before cooling) temperature of this water? 2)What is the final (after cooling) temperature of this water? 3)What is the final quality of this water? 4)How much does the specific internal energy of the water decrease?
