1. Five kilograms of water is contained in a piston-cylinder device; the water has initially a pressure of 100 kPa and a volume of 0.5 m (State 1). As shown in the diagram, the piston is connected to the rigid frame of the cylinder through a linear spring (which remains in contact with the piston and the rigid frame at all times). Heat is added to the water until the piston just hits the stops, at which point the water is in State 2. The temperature and volume of the water in State 2 are 400C and 1.6 m', respectively From State 2, heat addition is continued until the pressure of the water reaches 1.2 MPa (State 3). (a) Identify the phase of the water in State 1. Explain. (b) What is the specific volume of the water in State 2? (c) What is the pressure of the water in State 2 (in kPa)? (a) Determine the temperature of the water (in C) in State 3. (e) Show the process (from State 1 to State 3) on a P-v diagram; remember to include the saturation lines. (1) Determine the total boundary work done (in kJ) from State 1 to State 3. www HO
