The ratio of $ \frac{C_P}{C_V}$ for a diatomic gas is
Updated On: Apr 1, 2026
- $ \frac{5}{7} R$
- $ \frac{7}{9} R$
- $ \frac{5}{3} R$
- $ \frac{7}{5} R$

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
For a diatomic gas
$C_V = \frac{5}{2} R$ and $C_P = \frac{7}{5}R \:\:\:\: \therefore \:\: \frac{C_P}{C_V} = \frac{7}{5}$
In all the options R is given, it should not be there as $C_P/C_V$ is the ratio of two like quantities.
$C_V = \frac{5}{2} R$ and $C_P = \frac{7}{5}R \:\:\:\: \therefore \:\: \frac{C_P}{C_V} = \frac{7}{5}$
In all the options R is given, it should not be there as $C_P/C_V$ is the ratio of two like quantities.
