An engine operates in two successive Carnot cycles. The first cycle works between a hot reservoir at \(T_{H}=800\ \text{K}\) and an intermediate reservoir at temperature \(T_{M}\). The second cycle works between the intermediate reservoir at \(T_{M}\) and a cold reservoir at \(T_{C}=300\ \text{K}\). The total work produced per overall cycle is \(2000\ \text{J}\) and the heat rejected to the cold reservoir is \(1200\ \text{J}\). If the work done by the first Carnot engine equals the work done by the second Carnot engine, find the temperature \(T_{M}\) of the intermediate reservoir (in kelvin, to the nearest kelvin).
