ow to answer questions 21 to 23 A piston-cylinder contains 0.3 m of air at 100 kPa and 20°C. The air is compressed to a pessure of 800 kPa in a reversible polytropic process with an index of 1.2. Afterwards, it is expandaback to a pressure of 100 kPa in a reversible adiabatic process. Determine the following: 2 21. The air temperature at the end of compression (a) 171 °C (b) 258 °C (c) 444 °C (d) 531 °C
