Question

For a gas $\frac{R}{Cp}=0.4$.For this gas calculate the atomiclity and degree of freedom -

• A. $1$
• B. $\frac{F}{2}R$
• C. $\left(\frac{F+2}{2}\right)R$
• D. none of these

Answer 1

The correct option is C $\left(\frac{F+2}{2}\right)R$

$\begin{array}{c}{C}_p=\frac{1}{0.4}R=\frac{5}{g}R\\ C_r=\left(\frac{F}{2}R+R\right)=\left(\frac{F+2}{2}\right)R\end{array}$

Hence, option $C$ is the correct answer.
