- It both Assertion and Reason are true and the Reason is a correct explanation of the Assertion
- If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion
- If Assertion is true but the Reason is false
- If both Assertion and Reason are false
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The ratio $\frac{C_{p}}{C_{V}}$ is given by,
$\gamma=\frac{C_{p}}{C_{V}}=1+\frac{2}{n}$ where $n$ is the number of degrees of freedom. Since the number of degrees of freedom for monatomir. gas (3) is less than that of
diatomic gas (5), $\gamma_{\text {monatomic }}>\gamma_{\text {dlatiomic }}$
