Q. In the above question, if $\gamma = 1.5$, the gas may
A) Monoatomic
B) Diatomic
C) A mixture of monoatomic and diatomic gases
D) A mixture of diatomic and triatomic gases
Explanation
(c) For monatomic gas, $\eta = \frac{5}{3} = 1.67$
And for diatomic gas $\eta = \frac{7}{5} = 1.40$
As actual $\gamma = 1.5$. Therefore, gas must be a mixture of monoatomic and diatomic gases
