Is it possible to prove the first statement by conducting an experiment on water staining with a crystal of potassium permanganate? Think about what the phenomenon of diffusion of odors in the room indicates. Think about how to experimentally prove that particles of matter attract and repel.

The fact that substances are composed of particles can be proved by conducting an experiment on the color of water, because the phenomenon of diffusion (coloration of water, diffusion of odors) is proof that all bodies are composed of particles, and these particles are in continuous disorderly motion.
