Five kilograms of water initially at 4000 kPA, 200 degrres are contained in a piston-cylinder device. A variable force and appropriate energy transfers are applied to the piston so that the water temperature remains constant as wthe water expands to final volumesof .49m^3 and 1.7606m^3 in two processes. Sketch the processes on a T-v diagram relative to the saturation lines and determine the final pressure, the total volume change, and the total internal energy change of the water during these processes.
