A gas has $n$ degrees of freedom. The ratio of specific heat of gas at constant volume to the specific heat of gas at constant pressure will be :
Solution
<p>${C_V} = {{nR} \over 2}$</p>
<p>And ${C_P} = {{nR} \over 2} + R$</p>
<p>$$ \Rightarrow {{{C_V}} \over {{C_P}}} = {{{{nR} \over 2}} \over {{{nR} \over 2} + R}} = {n \over {n + 2}}$$</p>
