Question

What is Brownian motion? State four significant characteristics of Brownian

motion.

Answer 1

Brownian motion is the random movement of small particles suspended in a liquid or a gas.

Significance of Brownian motion

It tells us that particles are tiny nature and the particles of a matter are constantly moving.

Particles of matter have spaces between them.

Particles of matter are in continuous movement.

Vital evidence on the existence of atoms and molecules.

The kinetic theory of gases which explains that pressure, temperature and volume of gases are based on the Brownian motion.
