What is Brownian motion and what is it used to verify

The random movement of microscopic particles suspended in a liquid or gas, caused by collisions between these particles and the molecules of the liquid or gas.

Hey there :)

What is Brownian motion ?

Brownian motion is the random motion of particles suspended in a medium. The lower the viscosity of solvent, then more will be the speed with which the particle moves.

Examples :-

Some examples of Brownian motion include:-

☆ the motion of water molecules.

☆ The movement of dust particles.

It is used to verify what?

Brownian motion served as convincing evidence that atoms and molecules exist, and was further verified experimentally by Jean Perrin in 1908.

Consequence of it:-

Perrin was awarded the Nobel Prize in Physics in 1926 "for his work on the discontinuous structure of matter"
