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

Two different pure gases have the same tempereture. Do their molecules have the same rms speeds?

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

Two different gases at the same temperature have equal root mean square velocities.

The root mean square speed of gas molecules

At what temperature will be the oxygen molecules have the same root mean square root mean square speed as hydrogen molecules at 300 K ?

Root mean square speed of an ideal gas at 300 K is 500 m/s. Temperature is increased four times then root mean square speed will become
