An ideal gas (γ =1.5) is expanded adiabatically. How many times has the gas to be expanded to reduce the root mean square velocity of molecules 2.0 times?

Root mean square speed of the molecules of ideal gas is v. If pressure is increased two times at constant temperature, the rms speed will become

According to Maxwell's law of distribution of velocities of molecules, the most probable velocity is

To what temperature should the hydrogen at 327°C be cooled at constant pressure, so that the root mean square velocity of its molecules becomes half of its previous value?

At what temperature rms speed of air molecules is doubled of that at NTP?

Calculate the ratio of rms speeds of oxygen gas molecules to that of hydrogen gas molecules kept at the same temperature.

The root mean square velocity of gas molecules at 27 °C is 1365 ms ^-I . The gas is

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

The gas having average speed four times as that of SO₂ (molecular mass 64) is

Six molecules speeds are 2 units, 5 units, 3 units, 6 units, 3 units and 5 units, respectively. The rms speed is
