One mole of ideal monoatomic gas $(γ = 5/30)$ is mixed with one mole of diatomic gas $(γ = 7/5)$ . What is $γ$ for the mixture? $γ$ denotes the ratio of specific heat at constant pressure, to that at constant volume.

Options:

Answer:

Solution:

$Q = Q_{1} + Q_{2}$ $\frac{n _{1} + n _{2}}{γ _{m} - 1} = \frac{n _{1}}{γ _{1} - 1} + \frac{n _{2}}{γ _{2} - 1}$ $γ_{m} = \frac{3}{2}$
