Answer 2

(i) Brownian movement:

It is the random movement of the particles which is called as Brownian Movement.

This movement occurs because of the bombardment by other moving particles. Larger particles can be moved by light, fast moving molecules.

(ii) Diffusion:

Diffusion is a process in which the molecules move from high concentration to lower concentration.
