This exploration illustrates how a pool table and billiard balls serve as an effective visual analogy for the movement of particles in different states of matter—solids, liquids, and gases. Solids maintain a definite shape and volume with orderly particle arrangement. In contrast, liquids have a definite volume but adapt to the shape of their container, exhibiting more random atomic arrangements. Gases, on the other hand, have neither fixed shape nor volume, with particles moving freely. This analogy enhances understanding of the fundamental differences between these states.

DO NOW Explain how a pool table and billiard balls can be a good visual for the movement of particles.
Describing States of Matter Materials can be classified as a solid liquid or gas based on whether their shapes and volumes are definite or variable.
Solids Has a definite shape and definite volume Changing the container does not change the shape of the object Almost all solids have some type of orderly arrangement of the particles at the atomic level.
Liquids Have definite volume but variable shape Take the shape of their container Arrangement of atoms is more random than that of solids
