Problem

An industrial heat engine operates between

T_H = 500\,\text{K}

and

T_C = 300\,\text{K}

. If the engine absorbs

2.0\times10^{3}\,\text{J}

of heat per cycle from the hot reservoir, determine the minimum amount of heat (to the nearest joule) that must be rejected to the cold reservoir so that the Second Law is not violated. (a)

1.0\times10^{3}\,\text{J}

(b)

1.5\times10^{3}\,\text{J}

(c)

1.2\times10^{3}\,\text{J}

(d)

8.0\times10^{2}\,\text{J}
