Question 321: Thermodynamics & KTG

Question

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 :

Accepted Answer

$${C_V} = {{nR} \over 2}$$
And $${C_P} = {{nR} \over 2} + R$$
$$ \Rightarrow {{{C_V}} \over {{C_P}}} = {{{{nR} \over 2}} \over {{{nR} \over 2} + R}} = {n \over {n + 2}}$$

Answer

$$ \frac{n}{n+2}$$

Answer

$$ \frac{n+2}{n}$$

Answer

$$ \frac{n}{2n+2}$$

Answer

$$ \frac{n}{n-2}$$
