NEET Physics Kinetic Theory of Gases Questions Solved


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

1. V1+V2/2                           

2. V1

3. V1V21/2                               

4. 3 kT/M

2. Average speed of gas molecules is 8 kTπ m. It depends on temperature and molecules mass. So the

    average speed of O2 will be same in (A) and (C).
