In a solid...

• particles are spread out and move randomly

• particles are tightly packed in a regular structure

• particles are tightly packed but free to move past each other

In a liquid...

• particles are spread out and move randomly

• particles are tightly packed in a regular structure

• particles are tightly packed but free to move past each other

In a gas...

• particles are spread out and move randomly

• particles are tightly packed in a regular structure

• particles are tightly packed but free to move past each other
