0.2804 kg of nitrogen, originally in a cylinder at 200 kPa and 32 oC, is to be compressed  polytropically (PVn = C) to a final pressure of 1380 kPa. The volume compression ratio is 5:1. For  nitrogen, R = 297 J/kg.K and  = 1.41. Calculate: (a) The value of the index n (b) The work done during compression (c) The change in internal energy
