Problem

A reversible heat engine operates between a hot reservoir at

T_H = 500\,\text{K}

and a cold reservoir at

T_C = 300\,\text{K}

. If the engine absorbs

Q_H = 2000\,\text{J}

of heat from the hot reservoir in one cycle, determine the minimum amount of heat

Q_C

that must be rejected to the cold reservoir.
