A polyatomic ideal gas has \(24\) vibrational modes. What is the value of \(\gamma\) ?
- A \(1.03\)
- B \(1.30\)
- C \(1.37\)
- D \(10.3\)
Answer & Solution
Correct Answer
(A) \(1.03\)
Step-by-step Solution
Detailed explanation
Since each vibrational mode has 2 degrees of freedom hence total vibrational degrees of freedom \(=48\) \(f=3+3+48=54\) \(\gamma=1+\frac{2}{ f }=\frac{28}{27}=1.03\)
