50 ml of gas A diffuse through a membrane in the same time as 40 ml of a gas B under identical pressure-temperature conditions. If the molecular weight ofA is 64, that of B would be

0.5 mole of each of H₂, SO₂ and CH₄ are kept in a container. A hole was madein the container. After 3 hours, the order of partial pressures in the container will be

The rms velocity of an ideal gas at 27ºC is 0.3 ms^-1. Its r.m.s velocity at 927ºC (in m^-1) is

By how many folds the temp. of a gas would increase when the r.m.s velocity of gas molecules in a closed container of fixed volume is increased from 5 × 10⁴cms^-1 to 10 × 10⁴cms^-1

Ratio of C_p and C_vof gas ‘X’ is 1.4. The number of atoms of the gas ‘X’ present in 11.2 litres of it at N.T.P. is

The vapour density of a gas is 11.2. The volume occupied by 11.2 g of this gasat N.T.P. is

At 100ºC and 1 atm, if the density of liquid water is 1.0 g cm^-3 and that of water vapour is 0.0006 g cm^-3, then the volume occupied by water moleculesin 1 litre of steam at that temperature is

If X is the total number of collisions which a gas molecule registers with others per unit time under particular conditions, then the collision frequency of the gas containing N molecules per unit volume is

A gas is found to have a density of 1.80 g L^-1 at 760 mm pressure and 27ºC.The gas will be

4.0 g of argon (at mass = 40) in a bulb at a temperature of TK had a pressure P atm. When the bulb was placed in hotter bath at a temperature 50^o more than the first one, 0.8 g of gas had to be removed to get the original pressure.T is equal to
