Question

Equal volumes of two monoatomic gases, $A$ and $B$, at same temperature and pressure are mixed. The ratio of specific heats $\left(C_p/C_v\right)$ of the mixture will be:

• A. $1.50$
• B. $3.3$
• C. $1.67$
• D. $0.83$

Answer 1

Answer: (C)

$1.67$

For monoatomic
$\frac{C_p}{C_v}=\gamma =1.67$
$\because$ Equal volumes of two monoatomic gases so $\gamma$ will remain same.
