Problem

A cyclic heat engine absorbs

Q_H = 2000\,\text{J}

of heat from a hot reservoir and produces

W = 600\,\text{J}

of work. According to the Second Law, the minimum heat that must be rejected to the cold reservoir is: (a)

1200\,\text{J}

(b)

1400\,\text{J}

(c)

600\,\text{J}

(d)

0\,\text{J}
