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
$C_P=\frac{7}{2}Rand{C}_V=\frac{5}{2}R\Rightarrow {\gamma }_{di}=\frac{C_P}{C_V}=\frac{\frac{7R}{2}}{\frac{5R}{2}}=1.4$
