Three moles of oxygen are mixed with two moles of helium. What will be the ratio of specific heats at constant pressure and constant volume of the mixture?

Options:

Answer:

Solution:

$C_{v} = 3 \cdot \frac{5}{2} R + 2 \cdot \frac{3}{2} R = 10.5 R$

and $C_{p} = C_{v} + 5 R = 15.5 R$ . Ratio = $1.476$ , which is none of the

listed values. D.
