Mention the uses of Brownian movement.

Explanation

Brownian movementenables us,
i. to calculate Avogadro number.
ii. To confirm kinetic theory which cosiders the ceaseless rapid movement of molecules that increases with increase in temperature.
iii. To understand the stability of colloids: As the particles are in continuous rapid movement they do not come close and hence not get condensed. That is Brownian movement does not allow the particles to be acted on by force of gravity.
