Even two or three crystals of potassium permanganate can impart colour to a very large volume of water. Which characteristic of particles of matter is illustrated by this observation?

When crystals of potassium permanganate are placed at the bottom of a beaker of water, water in the whole beaker turns pink on its own. This process represents that matter is made up of small particles which diffuse from a region of higher concentration to a region of lower concentration. The phenomenon involved is known as diffusion.
