Five kg of carbon dioxide (CO2) gas undergoes a process in a well-insulated pistoncylinder assembly from 2 bar, 280 K to 20 bar, 520 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 5 0.939 kJ/kg ? K. (b) variable specific heats. Compare the results of parts (a) and (b).
