Question

Evidence for existence of particle in matter

Answer 1

Answer:

Explanation:

Matter is that occupies space and has weight. Everything around us is made up of particles. The particles which make up matter are so small that we cannot see them with a high power microscope. One of the characteristic of particle is that it constantly moves. Let us prove it through this article.

Everything around us is made up of tiny pieces or particles. The particles which make up matter are atoms or molecules. Our body, chair, table, book etc. all are made up of particles.

The evidence of the existence of particles in matter and their motion comes from the experiments on diffusion i.e. mixing of different substances on their own and Brownian motion. The zig-zag movement of the small particles suspended in a liquid or gas is called Brownian motion.
