Question: A heat engine operates on a Carnot cycle that runs clockwise between a reservoir at (340 mathrm{~K}) and a reservoir at (280 mathrm{~K}). One cycle

A heat engine operates on a Carnot cycle that runs clockwise between a reservoir at $340 \mathrm{~K}$ and a reservoir at $280 \mathrm{~K}$. One cycle moves enough energy from the hightemperature reservoir to raise the temperature of $1.0 \mathrm{~kg}$ of water by $1.0 \mathrm{~K}$. How much work is done by the engine in one cycle?
