Five kg of carbon dioxide (CO2) gas undergoes a process in a well-insulated piston–cylinder assembly from 2 bar, 280 K to 20 bar, 500 K. If the carbon dioxide behaves as an ideal gas, determine the amount of entropy produced, in kJ/K, assuming: (a) constant specific heats with cp = 0.939 kJ/kg · K. (b) variable specific heats.
