Question

Quizplus · Accepted Answer

The thermal efficiency for a non-Carnot heat engine is given by the formula $1 - \frac{Q_{\text{cold}}}{Q_{\text{hot}}}$, where $Q_{\text{cold}}$ is the heat expelled to the cold reservoir and $Q_{\text{hot}}$ is the heat absorbed from the hot reservoir. This matches the formula in choice C, albeit with some obfuscation due to the use of subscript and superscript formatting.
