Consider a system that consists of a piston-cylinder device with an attached linear spring, contains refrigerant R-134a. Initially, the system is at -32°C and has a quality of 30%, and the attached spring, which has a constant of 7 kN/m, exerts no force on the piston. It is also known that the initial volume is 0.1 m³. The 50 cm diameter cylinder is also fitted with stops. The device is then heated and the system expands until the piston hits the stops at which the volume is doubled. The heating is continued until the system reaches final temperature of 30°C. i. Calculate the amount of work (kJ) involved during the process ii. Calculate the heat transferred (kJ) during the process iii. Sketch the process on a P-v diagram with respect to saturation lines. Label the states clearly.
