(c) A piston-cylinder device contains 1.5 kg of nitrogen initially at 100 kPa and 17°C. The nitrogen is now slowly compressed in a polytropic process during which PV¹.3 = constant until the volume is reduced by one-half. (i) Determine the final pressure and temperature of nitrogen. (ii) Calculate the work input. (iii) Determine the heat transfer output. (iv) Show the process on a P-V diagram. (v) Propose TWO (2) assumptions for this polytropic process.
