Question

Which of the following gas has $\gamma$-value equal to 1.4?

• A. $He$
• B. $S{O}_2$
• C. $O_3$
• D. $O_2$

Answer 1

The correct option is D $O_2$

$\gamma =\frac{C_p}{C_v}$ is the ratio of specific heat.
It is a factor in adiabatic processes.
This ratio is equal to 1.4 for diatomic gas like $O_2$.
