Which outcome occurs when the heat input temperature decreases towards ambient in a Stirling engine?

💡 Explanation

Decreasing the hot reservoir temperature reduces the temperature differential used, thus reducing energy converted via the Carnot cycle; mechanical work is derived from this cycle. Because decreased differential energy will result rather than improve the efficiency, therefore work decreases.
