Answer :

★ Brownian movement :

It involves motion of colloidal particles in zig-zag paths. It is due to moving molecules of the dispersion medium which are constantly colliding with colloidal particles.

• It is observed in ordinary suspension.
• It offers a visible proof of the random kinetic motion of molecules in a liquid.
• It provides a direct demonstration of ceaseless motion of molecule as postulated by kinetic theory.
• It provide stability to colloidal sol by not allowing them to settle down$.$
