Three closed vessels A, B and C at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. Vessel A contains only
O2, B only N
2 and C a mixture of equal quantities of
O2 and N
2. If the average speed of the 0 2 molecules in vessel A is
v1,, that of the N
2 molecules in vessel B is v
2, the average speed of the
O2 molecules in vessel C is
where, M is the mass of an oxygen molecule
