q) Three closed vessels A,B and C are at the same temperature T and contain gases which obey the Maxwellian distrubution 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 O₂ molecules in vessel C is ...?
