Match the temperatures of the source and sink ( \(T_1\) and \(T_2\) respectively) of a Carnot heat engine given in List-I with the corresponding efficiencies given in List-II.

The correct match is Codes
\(\begin{array}{llll}
A & B & C & D
\end{array}\)
- A (iii) (iv (ii) (i)
- B (iv) (iii) (ii) (i)
- C (iii) (i) (iv) (ii)
- D (iii) (ii) (iv) (i)
Answer & Solution
Correct Answer
(D) (iii) (ii) (iv) (i)
Step-by-step Solution
Detailed explanation
Key Ideal Efficiency of a Carnot engine is given as, \[ \eta=1-\frac{T_2}{T_1} \] where, \(T_1=\) surface temperature and \(T_2=\sin k\) temperature. Now, the efficiencies are, (a) When \(T_1=500 \mathrm{~K}, T_2=300 \mathrm{~K} \Rightarrow \eta=1-\frac{300}{500}=0.4\) (b) When…
