Define: (1) Diffusion (2) Brownian Movement (3) Boiling Point



(1) Diffusion:

The spreading of ni.olecules of a substance through a medium like air or liquid; due to kinetic molecular motion is called Diffusion.

(2) Brownian Movement:

A continuous, rapid, zig-zag motion of suspended particles through the medium is called Brownian movement. The suspended particles are made to move due to the kinetic molecular motion of molecules of a medium.

(3) Boiling Point:

The boiling point is the temperature at which a liquid boils. It is the temperature at which vapour pressure of liquid becomes equal external pressure.
