The electric power is supplied at a rate of 200 W and the shaft power is supplied at a rate of 1.6 kW. During this process, the gas loses 78 kJ of heat to the surroundings and experiences a rise in internal energy of 120 kJ/kg. How much boundary work is done during this process? [Wb] kJ This is work [inout] (into/out of) the system.
