Three closed vessels ‘A’,‘B’ and ‘C’ are at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. Vessel ‘A’ contains only O2, ‘B’contains only N2 and ‘C’ a mixture of equal quantities of O2 and N2. If the average speed of the O2 molecules in vessel ‘A’ is ′v1′ that of the N2 molecules in vessel B is ′v2′ then the average speed of the O2 molecules in vessel ‘C’ is (where ‘M’ is the molecular mass of an oxygen molecule and ‘K’ is the Boltzmann’s constant)
