Carbon monoxide is carried around a closed cyclic processes `abc`, in which `bc` is an isothermal process, as shown in Fig. The gas absorbs `7000 J` of heat as its temperature is increased from `300 K` to `1000 K` in going from `a` to `b`. The quantity of heat ejected by the gas during the process `ca` is
