Problem
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 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 and that of the N2 molecules in vessel B is v2, what is the average speed of the O2 molecules in vessel C?
(1) 2v1+v2
(2) v1
(3) (v1⋅v2)2
(4) M3kT
