1. Carbon dioxide (CO2) gas undergoes a process in a well-insulated piston-cylinder assembly from P1 = 2 bar, T1 = 300 K to P2 = 20 bar, T2 = 1700 K. Assuming this CO2 behaves like an ideal gas: (a) What is the intensive entropy change using a constant, average value for heat capacity that represents the relevant range of process conditions? (b) What is the intensive entropy change accounting for the change of specific heat with temperature? (c) what is the percent difference between results using the different models? (d) which of these is most accurate, why? (e) for case (b), what is the entropy generation for this process?
