Question

Describe the particle model of matter.what does the Brownian motion tells us about the particles in matter?give other evidence to support the existence of particles that make up matter.

Answer 1

The particle model of matter states " All matter is made of up particles, these particles behave in different ways whether they are solid, liquid or gas." Brownian motion tells us that particle of matter especially the gas particles are in continuous random motion, they collide with one another and change directions.
other evidence for the existence of particles is the motion of smoke particles.

Answer 2

Answer:

In the particle model of matter,matter is made up of tiny district which are in constant and random motion.Brownian motion provides evidence that particles that make up matter are moving constantly and randomly.(Hope it helps)
