3. A piston-cylinder device with a volume of 0.035 m (refer Figure below) contains refrigerant R134-a at 400 kPa (State 1). Initially 20% of the volume is liquid and the rest is vapor. Then heat is added to the system until the piston is just touching the stopper (State 2). At this state, all the R-134a exists 100% as vapor. Heating is continued until the pressure inside the piston reaches 600 kPa (State 3). stopper Q R-134a a. What is the total mass and quality of refrigerant R-134a inside the piston at initial state. (5 marks) b. Determine the boundary work from State 1 to State 3 (in kJ). (10 marks) Determine the amount of heat from State 1 to State 3 (in kJ). (10 marks) d. Show theses processes on a well-labled T-v and P-v diagrams. (5 marks) C
