tgv4vn m;31ez 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
4vn1gme;3t v zsurroundings. How much heat is expelled by the gas during process C → D?
