A Heat Engine Absorbs Energy of Magnitude $\mid$ Q_H $\mid$ From a High Temperature Reservoir, Does Work of Magnitude

question 54

Multiple Choice

A heat engine absorbs energy of magnitude $\mid$ Q_H $\mid$ from a high temperature reservoir, does work of magnitude $\mid$ W $\mid$ , and transferes energy of magnitude $\mid$ Q_L $\mid$ as heat to a low temperature reservoir. Its efficiency is:

• A) \(\mid\)Q_H \(\mid\)/ \(\mid\)W \(\mid\)
• B) \(\mid\)Q_L \(\mid\)/ \(\mid\)W \(\mid\)
• C) \(\mid\)Q_H \(\mid\)/ \(\mid\)Q_L \(\mid\)
• D) \(\mid\)W \(\mid\)/ \(\mid\)Q_H \(\mid\)
• E) \(\mid\)W \(\mid\)/ \(\mid\)Q_L \(\mid\)
