A piston-cylinder device contains the refrigerant R-134a at 600 kPa with a quality of 95%. The volume at this state is 0.3 m3. The piston is then allowed to move such that during this process, -30 kJ of work is performed white the pressure is held constant. Determine the final temperature and quality for this process

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
