Ideal gas is compressed polytropically along a path for which n = 1.30 in a closed system. The initial temperature and pressure are 17 C and 100 kPa, respectively, and the final pressure is 500 kPa. Assume R = 0.287 kJ/kg K and average specific heats cv = 0.723 kJ/kg.K and cp = 1.01 kJ/kg.K. Calculate: a) the final temperature in K; (10 marks) b) the work done on the gas, in kJ/kg; (10 marks) c) the amount of heat. (10 marks) d) entropy change for the process (10 marks)
