Molecular hydrogen at one atmosphere and helium at two atmosphere occupy volume `V` each at the same temperature. The rms velocity of hydrogen molecules is `x` times the rms velocity of helium molecules. What is the value of `x`?

The temperature at which rms velocity of helium molecules is equal to the rms velocity of hydrogen molecules at NTP is

Temperature at which the rms velocity of oxygen molecules will be equal to that of helium molecules at NTP is

Calculate the RMS velocity of hydrogen molecule at 0^@C .

At what temperature will the rms velocity of SO_(2) molecules be equal to the rms velocity of O_(2) molecules at 25^(@)C ?

The temperature of H_(2) at which the rms velocity of its molecules is seven times the rms velocity of the molecules of nitrogen at 300 K is

The temperature of H_2 at which the rms velocity of its molecules is seven times the rms velocity of the molecules of nitrogen at 300 K is :

The rms velocity of hydrogen is sqrt(7) times the rms velocity of nitrogen. If T is the temperature of the gas, then

Two vessels having equal volume contain molecular hydrogen at one atmosphere and helium at two atmospheres respectively. What is the ratio of rms speeds of hydrogen molecule to that of helium molecule if both the samples are at same temperature.
