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, that of the N2 molecules in vessel B is v2, the average speed of the O2 molecules in vessel C is
- \(\frac{v_{1}+v_{2}}{2}\)
- \(v_{1}\)
- \(\sqrt{v_{1} v_{2}}\)
- \(\sqrt{\frac{3 \mathbf{k} T}{\mathrm{M}}}\)
Answer
(B) v_ 1
