For this problem model air as a perfect gas with specific heat capacity at constant pressure C_p-1,004 J/kg/K, and gas specific constant R= 286.96 J/kg/K. The environment is at 101.3 kPa and 288 K. A perfectly insulated container of negligible heat capacity contains 10 kg air, initially at atmospheric temperature. An electric resistance heater at constant temperature T_H-800 K is placed inside the container and used to increase the temperature of air to 400 K. What is the energy increase of the air in the container, what is the energy supplied by the resistance heater, and what is the entropy generated by irreversibility in the two distinct cases below? (a) The container is a constant volume container. [DS_ir= 1,351.65 J/K] (b) The container is a constant pressure container, kept at atmospheric pressure. [DS_ir= 1,802.58 J/K] [10 points]
