The ratio of rates of diffusion of gases X and Y is 1 : 5 and that of Y and Z is 1 : 6. The ratio of rates of diffusion of Z and X is [EAMCET 2014]

Which among the following gases can be liquified easily? [MH-CET 2014]

Four gases P, Q, R and S have almost same values of ‘b’ but their ‘a’ values (a, b are van der Waals constants) are in the order Q < R < S < P. At a particular temperature, among the four gases the most easily liquefiable one is [WBJEEM 2014]

If average velocity of a sample of gas molecules at 300 K is 5 cm s^–1, what is RMS velocity of same sample of gas molecules at the same temperature ? (Given, α : u : v = 1 : 1.224 : 1.127) [MH-CET 2014]

At a certain temperature the time required for the complete diffusion of 200 mL of H₂ gas is 30 minutes. The time required for the complete diffusion of 50 mL of O₂ gas at the same temperature will be [WBJEEM 2014]
