There are three fundamentally known states of matter save for plasma and the Bose-Einstein condensate. These states of matter are solid, liquid and gas.
We can classify nearly all matter into these discrete categories based on certain lucid characteristics they exhibit.
Solids have definite shape and volume and they exhibit by the far the most remarkable internal ordering. Their molecules are attached by strong internal forces.
Liquids do not have a definite shape but takes the shape of the contains that hold them. They are not random and have internal cohesion among them.
Gases are random particles and highly varied. They move haphazardly and have no definite shape and volume.
