- A \(6\)
- B \(3.5\)
- C \(2.5\)
- D \(1.4\)
Answer & Solution
Correct Answer
(D) \(1.4\)
Step-by-step Solution
Detailed explanation
The ratio of specific heats at constant pressure \(\left(\mathrm{C}_{\mathrm{p}}\right)\) and constant volume \(\left(\mathrm{C}_{\mathrm{v}}\right)\) \(\frac{C_{p}}{C_{v}}=\gamma=\left(1+\frac{2}{f}\right)\) where fis degree of freedom…
