If one mole of the polyatomic gas is having two vibrational modes and $β$ is the ratio of molar specific heats for polyatomic gas $(β = \frac{C_{P}}{C_{v}})$ then the value of $β$ is :

Options:

Answer:

Solution:

$f = 4 + 3 + 3 = 10$ , assuming non-linear,

$β = \frac{C_{p}}{C_{v}} = 1 + \frac{2}{f} = \frac{12}{10} = 1.2$
