# NEET Physics Kinetic Theory of Gases Questions Solved

Three closed vessels A, B and C are at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. Vessel A contains only  only ${\mathrm{N}}_{2}$ and C a mixture of equal quantities of ${\mathrm{O}}_{2}$ and ${\mathrm{N}}_{2}$. If the average speed of the ${\mathrm{O}}_{2}$ molecules in vessel A is  that of the ${\mathrm{N}}_{2}$ molecules in vessel B is  the average speed of the ${\mathrm{O}}_{2}$ molecules in vessel C is

1. $\left({\mathrm{V}}_{1}+{\mathrm{V}}_{2}\right)/2$

2. ${\mathrm{V}}_{1}$

3. ${\left({\mathrm{V}}_{1}{\mathrm{V}}_{2}\right)}^{1/2}$

4.

2. Average speed of gas molecules is  It depends on temperature and molecules mass. So the

average speed of ${\mathrm{O}}_{2}$ will be same in (A) and (C).
