Two vessels of the same volume and filled with the same gas at the same temperature. If the pressure of the gas in these vessel be in the ratio 1:2, then state : (i) the ratio of the rms speeds of the molecules, (ii) the ratio of the number of molecules.

Two vessels of the same volume contain the same gas at same temperature. If the pressure in the vessels is in the ratio of 1 : 2, then

Two identical vessels contain two different ideal gases at the same temperature. If the average speed of gas molecules in the first vessel is euqal to the most probable speed of molecules in the second vessel, then the ratio of the mass of gas molecules in the first vessel to that in the second vessel 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

Oxygen and hydrogen gas are at same temperature and pressure. And the oxygen molecule has 16 times the mass of hydrogen molecule. Then the ratio of their rms speed is

Volume of vessel A is twice the volume of vessel B. Both are filled with the same gas. If gas in A is at twice the temerature and twice the pressure to the gas in B, what is the ratio of gas molecules in A and B ?

Equal masses of the two gases A and B are kept in two separate vessels at the same temperature and pressure. If the ratio of the molecular masses of A and B is 2 : 3 , find the ratio of the volumes of the two vessels.

The ratio of average speed of an O_(2) molecule to the rms speed of N_(2) molecule at the same temperature is

There are 4 xx 10^(24) gas molecules in a vessle at 50 K temperature. The pressure of the gas in the vessel is 0.03 atm . Calculate the volume of the vessel.

The ratio of rms speed of an ideal gas molecules at pressure p to that at pressure 2p is
