A piston-cylinder device fitted with stops (as shown below) contains water at 200 kPa and 300 C (State 1). It is cooled at a constant pressure until the piston hits the stops. At that stage (State 2), the state of the water is found to be saturated vapor (the right-hand corner of the horizontal line). What is the temperature and the specific volume of the water at State 2? [2 points] As the piston has hit the stops, the volume from State 2 on is constant. The water is then cooled (at constant volume) until the pressure is 100 kPa (State 3). What is the quality of the water at State 3? [6 points] What is the temperature at State 3? [2 points] What is the change in internal energy from State 1 to State 3? [5 points] In a neat, properly drawn (with a straight edge, and suitably scaled) T-v plot-space locate States 1, 2 and 3 and trace the process path. [5 points] O on Water 200 kPa 300C
