PMM

PMM or Particle Model of Matter is a set of laws, or a model, developed to help us better understand the way matter works and reacts in different situations.

The Laws

All Matter is Made of Particles

The first law tells us that all matter is made up of one universal substance; particles. Particles are so small they can not be seen with the naked eye or any form of optical device that humans have made.

All Particles are Constantly Moving or Vibrating

Particles within a substance are constantly in motion. Particles within a gas move relatively freely and quite fast in comparison to particles in other forms of matter. Particles in a liquid move fast, but not as fast as particles in a gas and more fast than particles in a solid. Particles within a solid move quite slowly and even may slow down to a point at which they vibrate.

All Particles Have Spaces Between them

Adding Heat to Particles Makes them Move Faster and vice versa
