The efficiency of Carnot heat engine
- A is independent of the temperature of the source and the sink
- B is independent of the working substance
- C can be \(100 \%\)
- D is not affected by the thermal capacity of the source or the sink
Answer & Solution
Correct Answer
(B) is independent of the working substance
Step-by-step Solution
Detailed explanation
We know that, the efficiency of Carnot heat engine is \[ \eta=1-\frac{T_2}{T_1} \] where, \(T_1=\) temperature of source (hot reservoir) \(T_2=\) temperature of sink (cold reservoir) Hence, efficiency depends only on the temperature of hot and cold reservoir but independent of…
