If one mole of the polyatomic gas is having two vibrational modes and \(\beta\) is the ratio of molar specific heats for polyatomic gas \(\left(\beta=\frac{ C _{ P }}{ C _{ v }}\right)\) then the value of \(\beta\) is:
- A \(1.02\)
- B \(1.2\)
- C \(1.25\)
- D \(1.35\)
Answer & Solution
Correct Answer
(B) \(1.2\)
Step-by-step Solution
Detailed explanation
\(f=4+3+3=10\) assuming non linear \(\beta=\frac{C_{p}}{C_{v}}=1+\frac{2}{f}=\frac{12}{10}=1.2\)
