A monatomic ideal gas is used as the working substance for the cycle shown in the figure.Preocesses A → B and C → D are isothermal, while processes B → C and D → A areadiabatic. During process A → B , there is 400 J of work done by the gas on thesurroundings. Calculate how much heat (in 100 Joules) is expelled by the gas during processC → D ?
