Two process which provides the best evidence for the motion of particles in matter are :
1. Brownian Motion
2. Diffusion.
Brownian Motion
---> The best evidence for existence and movement of particles in liquids was given by Robert Brown.
----> The zig zag movement of the small particles suspended in a liquid[gas]
Diffusion:
The spreading and mixing of a substance with another substances due to its motion of its particles is called as Diffusion.
The existence of Brownian motion and diffusion gives us two conclusion about:
---->that matter is made up of tiny particles.
---->That the particles of matter are constantly moving.
