Problem

A heat engine absorbs

600\,\text{J}

of energy as heat from a

800\,\text{K}

reservoir and rejects energy to a

300\,\text{K}

sink. Each cycle generates

0.15\,\text{J}\!/\!\text{K}

of entropy internally. Assuming no other energy interactions, what is the actual work produced per cycle? a)

315\,\text{J}

330\,\text{J}

285\,\text{J}

375\,\text{J}
