The Particle Theory of Matter

Everything you can see around you is made of particles

Particles are very small portions of matter

THE PARTICLE THEORY OF MATTER is a theory which explains the behaviour of all matter.

The Particle Theory states that:

  • All matter is made up of particles

  • All particles in the of one substance are identical

  • Particles are in constant motion.

  • Particles move and vibrate constantly because they have

 

Gas particles have more kinetic energy than solid particles. Liquid particles have more kinetic energy than a solid but less than a liquid.

 

  • Temperature affects the speed at which particles move.

  • Temperature is a measure of the average kinetic energy the particles have. The higher the temperature, the more energy they have.

  • Particles have forces of attraction between them

  • There are spaces between the particles
