Question 90 of 168

A polyatomic ideal gas has $24$ vibrational modes. What is the value of $\gamma ?$

Show answer and solution

Answer: (A) $1.03$

Since each vibrational mode has

2

degrees of freedom hence total vibrational degrees of freedom

=48

f=3+3+48=54

\gamma =1+\dfrac{2}{f}=\dfrac{28}{27}=1.03
