  03.47: A monatomic ideal gas is used as the worke8b8ynp7i -ka ;za s8aing substance for the Carnot cycle shown in the figure. Processes A → B and C → D are isot8az7; aek- ybnsia88phermal, 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?
