A Carnot engine operates between a hot reservoir at $394\mathrm{.}0$K and a cold reservoir at $304\mathrm{.}0$K$.$ If it absorbs $485\mathrm{.}0$J of heat per cycle at the hot reservoir, how much work per cycle does it deliver?

$$Tries $0/10$

If the same engine, working in reverse, functions as a refrigerator between the same two reservoirs, how much work per cycle must be supplied to remove $940\mathrm{.}0$ J of heat from the cold reservoir?

How much heat per cycle is exhausted to the kitchen?
