Everyday Science / Physics — Multiple-choice practice
- A. The efficiency of the working substances
- B. The ideal gas scale temperature
- C. The thermal conductivity of the working substances
- D. The thermal conductivity of the working substances
Correct answer
The efficiency of the working substances
Explanation
Explanation The efficiency of a Carnot engine is defined as the ratio of the heat absorbed from the hot reservoir (heat accepted) to the heat rejected to the cold reservoir (heat rejected). This efficiency is directly related to the temperature difference between the two reservoirs.
