The constant motion and high velocities of gas particles lead to some important practical consequences. One such consequence is that gases mix rapidly when they come in contact. Take the stopper off a bottle of perfume, for instance, and the odour will spread rapidly through the room as perfume molecules mix with the molecules in the air. This mixing of different gases by random molecular motion and with frequent collision is called diffusion. A similar process in which gas molecules escape without collision through a tiny hole into a vaccum is called effusion. Both the processes follow Graham’s law which is mathematically put as . The average distance travelled by molecules between successive collisions is called mean free path

Answer the following questions on the basis of the above information:

The stopcocks of the bulbs  (containing ) and  (containing ), both under identical conditions, are opened simultaneously. White fumes of , are formed at point . If =36.5 cm, then  is approximately

a)

18.0 cm

b)

25.0 cm

c)

20.0 cm

d)

36.5 cm
