03.47: A monatomic idealauv2k9+pbc/4if xtj8 gas is used as the working substance for the Carnot cycle shown in the figure. Processes A → B and C → D are isothermal, while processes B → C and D → A are adiabatic. During process A → B, there are 400 J of work done by the gas on the surroundings. How much heat is expelled by the gas during process C → D?8k/iax4 bpfj9cvu2+ t
