The ratio of rms velocities of two gases at the same temperature is `1: sqrt(2)`. Compare the vapour densities of the gases.

The ratio of vapour densities of two gases at the same temperature is 8:9. Compare the rms velocities of their molecules.

The ratio of vapour densities of two gases at the same temperature is 8:9. Compare the r.m.s. velocities of their molecules

The ratio of the vapour densities of two gases at the same temperature is 8:9 . The ratio of the rms velocities of their molecules is

The ratio of the vapour densities of two gases at the same temperature is 8:9 . The ratio of the rms velocities of their molecules is

The ratio of the vapour densities of two gases at a given temperature is 9:8 . The ratio of the r_(rms) velocity of their molecules is

v_(1) and v_(2) are the velocities of sound at the same temperature in two monoatomic gases of densities

Will the rms speed of molecules of different gases at the same temperature be the same?
