(a) A Carnot engine operates between a hot reservoir at 320K and a cold one at 260K. If the engine absorbs 500J as heat per cycle at the hot reservoir, how much work per cycle does it deliver?

(b) If the engine working in reverses functions as a refrigerator between the same two reservoirs, how much work per cycle must be supplied to remove 1000J as heat from the cold reservoir?
