Question:
If one mole of the polyatomic gas is having two vibrational modes and $\beta$ is the ratio of molar specific heats for polyatomic gas $\left(\beta=\frac{\mathrm{C}_{\mathrm{P}}}{\mathrm{C}_{\mathrm{v}}}\right)$ then the value of $\beta$ is :
Correct Option:
Solution:
(2)
$f=4+3+3=10$
assuming non linear
$\beta=\frac{C_{p}}{C_{v}}=1+\frac{2}{f}=\frac{12}{10}=1.2$
