Final answer:
A heat engine would be more efficient in a higher temperature environment due to the temperature difference affecting its efficiency.
Explanation:
A heat engine would be more efficient in an environment with a higher temperature. This is because the efficiency of a heat engine is determined by the temperature difference between the hot and cold reservoirs, as described by the Carnot efficiency formula. With a higher temperature on the hot side, more work can be extracted from the heat energy input.
