A reversible steady device puts out \(W_{\text {out }}=750 \mathrm{~J}\) of mechanical energy. The only input energy is the quantity \(Q_{\text {in }}\) transferred thermally from a thermal reservoir at \(355 \mathrm{~K}\). If the temperature of the environment (which serves as a low-temperature reservoir) is \(300 \mathrm{~K}\), what quantity of energy \(Q_{\text {out }}\) is transferred thermally out of the device?
