States of Matter

Matter can exist in three different states.

Solids are defined by these characteristics:
Definite shape
Definite volume
Particles vibrate in place

Liquids have the following characteristics:
No definite shape.  Takes the shape of the container.
Has definite volume.
Particles are free to move over each other, but are still attached.

Gases have the following characteristics:

No definite shape. Takes the shape of its container.

No definite volume.

Particles move in random motion without any attraction to each other, except maybe random collisions.

If matter is tightly packed together it is very dense.

If the particles are very spread apart they are not very dense.

Those are the 3 states of matter...there is a fourth.  Plasma! 

Plasma! Super. Heated. Particles.  Saved the best for last.
