A a carnot engine operates between a hot reservoir at 47c, Ask an Expert

Academics

(a) A carnot engine operates between a hot reservoir at 47C and a cold one at -13C. 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 reverse functions as a refrigerator between the same 2 reservoirs, how much work per cycle must be supplied to remove 1000J as heat from the cold reservoir?
