The efficiency of an ideal Carnot engine working between temperatures \(T_1\) and \(T_2\) is \(1 / 3\). If the temperature of the sink is reduced by \(40 \%\), then its efficiency will be
- A \(50 \%\)
- B \(25 \%\)
- C \(60 \%\)
- D \(75 \%\)
Answer & Solution
Correct Answer
(C) \(60 \%\)
Step-by-step Solution
Detailed explanation
Efficiency of Carnot engine, \(\eta=\frac{1}{3}\) But \(\eta=1-\frac{T_2}{T_1}\) where, \(T_1=\) and temperature of fource \(T_2=\) temperature of sink.…
