Particle Theory of Matter • All matter is made of tiny particles; differentsubstances are made of different particles • The particles in matter are bonded to one another 3) Particles of matter are always moving and vibrating 4) Particles have spaces between them; these spaces are different in solids, liquids and gases
3 Properties of Fluids • Viscosity - Liquid’s internal resistance or friction that keeps it from flowing - Fluids with high viscosity don’t flow as well
