1. A piston/cylinder compressor takes R-410a as saturated vapor 500 kPa and compresses it in a reversible adiabatic process to 3000 kPa. Find the final temperature and the specific compression work.
2. A piston/cylinder receives R-410a at 500 kPa and compresses it in a reversible adiabatic process to 1800 kPa, 60?C. Find the initial temperature.
