Current Question (ID: 19851)

Question:
$\text{A gas has } n \text{ degrees of freedom. The ratio of the specific heat of the gas at constant volume to the specific heat of the gas at constant pressure will be:}$
Options:
  • 1. $\frac{n}{n+2}$
  • 2. $\frac{n+2}{n}$
  • 3. $\frac{n}{2n+2}$
  • 4. $\frac{n}{n-2}$
Solution:
$\text{Hint: } C_V = \frac{nR}{2}$ $\text{Step: Find the ratio of } \frac{C_V}{C_P}. $ $\text{The ratio of the specific heat of the gas at constant pressure to the specific heat of the gas at constant volume is given by:}$ $\gamma = \frac{2}{f} + 1$ $\Rightarrow \gamma = \frac{2+f}{f}$ $\Rightarrow \frac{C_V}{C_P} = \frac{1}{\gamma} = \left( \frac{n}{n+2} \right)$ $\text{Hence, option (1) is the correct answer.}$
