Two reversible refrigeration cycles operate in series. The first cycle receives energy by heat transfer from a cold reservoir at 300 K and rejects energy by heat transfer to a reservoir at an intermediate temperature T greater than 300 K. the second cycle receives energy by heat transfer from the reservoir at temperature T and rects energy by heat transfer to higher-temperature reservoir at 883 K. if the refrigeration cycles have the same coefficient of performance determine (a) T, in K, and (b) the value of each coefficient of performance.
