# NEET Physics Kinetic Theory of Gases Questions Solved

If  and ${\mathrm{V}}_{\mathrm{O}}$ denote the root-mean square velocities of molecules of hydrogen, nitrogen and oxygen respectively at a given temperature, then

1. ${\mathrm{V}}_{\mathrm{N}}>{\mathrm{V}}_{\mathrm{O}}>{\mathrm{V}}_{\mathrm{H}}$

2. ${\mathrm{V}}_{\mathrm{H}}>{\mathrm{V}}_{\mathrm{N}}>{\mathrm{V}}_{\mathrm{O}}$

3. ${\mathrm{V}}_{\mathrm{O}}>{\mathrm{V}}_{\mathrm{N}}>{\mathrm{V}}_{\mathrm{H}}$

4. ${\mathrm{V}}_{\mathrm{O}}>{\mathrm{V}}_{\mathrm{H}}>{\mathrm{V}}_{\mathrm{N}}$
