The most probable speed of 8 g of H_(2) 200 ms^(-1) average kinetic energy (neglect rotational and vibrational energy) of H_(2) gas is :

The root mean square speed of molecules of ideal gases at the same temperature are

(A): Different gases at the same conditions of temperature and pressure have different root mean square velocities. (R ):Average kinetic energy of gas is directly proportional to absolute temperature.

At what temperature is the root mean square speed of an atom in an argon gas cylinder equal to the rms speed of a helium gas atom at -20^(@)C ? (atomic mass of Ar = 39.9 u, of He = 4.0 u) .

(A): Internal energy of an ideal gas sample is total kinetic energy of the gas (R ): There is no interaction force between gas molecules hence potential energy is not defined

The most probable speed of helium molecules is same as the root mean square speed of neon molecules. If the temperature difference of the two gases be 150°C, the temperature of neon is:

The root mean square speed of an ideal gas is given by : u_("rms") = sqrt((3RT)/M) Thus we conclude that u_("rms") speed of the ideal gas molecules is proportional to square root of the temperature and inversely proportional to the square root of the molar mass. The translational kinetic energy per mole can also be given as 1/2Mu_(rms)^(2) . The mean free path ( lambda ) is the average of distances travelled by molecules in between two successive collisions whereas collision frequency (C.F.) is expressed as number of collisions taking place in unit time. The two terms lambda and C.F. are related by : C.F = (u_("rms")/lambda) A jar contains He and H, in the molar ratio 1 : 5. The ratio of mean translational kinetic energy at the same temperature is

At 400 K, the root mean square (rms) speed of a gas X (molecular weight = 40) is cgual to the most probable speed of gas Y at 60K. The molecular weight of the gas Y is
