Problem

A heat engine operates between a hot reservoir at

700\,\text{K}

and a cold reservoir at

350\,\text{K}

. If it absorbs

1000\,\text{J}

of heat from the hot reservoir in each cycle, the least amount of heat that must be rejected to the cold reservoir so that the Second Law is not violated is (a)

350\,\text{J}

(b)

500\,\text{J}

(c)

0\,\text{J}

(d)

700\,\text{J}
