Density is a measurement of how much stuff is in a specific space.

Everything is made up of tiny particles ~ called atoms.   Those particles are attracted to each other.  

 

 

The state of matter of an object depends on how much energy the particles have.

 

 

In a solid ~ the particles seem to be bound tightly ~ they can only vibrate.

 

In a liquid ~ the particles do not have such a tight bond, they can slide pass each other.

 

In a gas ~ the particles are on their own, flying around, colliding, and ricocheting off each other.
