Question

The ratio of two specific heats $\frac{C_p}{C_v}$ of CO is

• A. 1.33
• B. 1.4
• C. 1.29
• D. 1.66

Answer 1

The correct option is B 1.4

CO is diatomic gas, for diatomic gas
$C_p=\frac{7}{2}R$ and $C_v=\frac{5}{2}R\Rightarrow \gamma =\frac{C_p}{C_v}=\frac{\frac{7R}{2}}{\frac{5R}{2}}$ = 1.4
