This document discusses the three states of matter - solid, liquid, and gas. It describes solids as having a definite volume and shape that does not change with the container. Solid particles are arranged in a regular pattern with little movement. Liquids also have a definite volume but take the shape of their container, and particles can move past one another. Gases have no definite volume or shape, filling their container completely, and particles are very far apart moving randomly.

• The Solid State:
• A solid has a definite volume.
• It maintains its shape regardless
of its container.
• Solid particles lie close together
in a regular pattern.

The Liquid State:
• A liquid has a definite volume.
• It takes the shape of its
container.
• Liquid particles are close together
but can move past one another.

States of Matter
The Gas State:
• A gas has no definite shape;
it assumes the shape of its
container.
• It has no definite volume; it
assumes the volume of its
container.• Gas particles are very far apart and
move around randomly.
