Physics - Heat & Thermo Question with Solution | TestHub

${\gamma }_{\mathrm{A}}$ is the specific heat ratio of monoatomic gas A having 3 translational degrees of freedom. ${\gamma }_B$ is the specific heat ratio of polyatomic gas B having 3 translational, 3 rotational degrees of freedom and 1 vibrational mode. If $\frac{{\gamma }_{\mathrm{A}}}{{\gamma }_{\mathrm{B}}}=\left(1+\frac{1}{\mathrm{n}}\right)$, then the value of $n$ is _______.
