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
