give evidence of molecules (particles of matter)?

Characteristics of Particles of Matter
These are the four main characteristics of particles of matter :
Particles of matter are very tiny in size.
They have spaces between them.
Particles of matter move constantly.
They are attracted towards each other.
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.
hope it helps............
Today we use the word atom to describe the tiny particles that make up all forms of matter. Molecules are combinations of atoms. ... You may wonder how we know about atoms if they are so small. Many experiments can give evidence for the existence of atoms and molecules.
