Solution
Correct Answer:
End temperatures
The Carnot cycle is an idealized thermodynamic cycle that provides the maximum possible efficiency for a heat engine.
- The efficiency (η) of a Carnot engine is given by: η=1−ThotTcold where T must be in Kelvin.
- Significantly, this efficiency is independent of the working substance (it doesn't matter if it's air, steam, or an ideal gas) and depends only on the temperatures of the source and the sink.
This easy difficulty physics question is from the chapter thermodynamics, covering the topic of carnot efficiency. It appeared in the 2025 exam.
