The following four gases are at the same temperature. In which gas do the molecules have the maximum root mean square speed?

Two different gases have exactly the same temperature.Does this mean their molecules have the same rms speed?

Two different gases have exactly the same temperature. Does this mean that their molecules have the same r.m.s. speed?

Following gases are kept at the same temperature. Which gas possesses maximum r.m.s. speed?

At what temperature will the oxygen molecules have the same root mean square speed as hydrogen molecules at 200K

At what temperature will hydrogen molecules have the same root mean square speed as nitrogen molecules at 27^(@)C ?

At what temperature will hydrogen molecules have the same root mean square speed as nitrogen molecules at 27^(@)C ?

The root mean square speed of the molecules of a diatomic gas is v. When the temperature is doubled, the molecules dissociates into two atoms. The new root mean square speed of the atom is
