States of Matter

The three most common states of matter are solid, liquid, and gas. Each state has its own unique properties and behaviors.

Solid

A solid is a state of matter that has a definite shape and volume. The particles in a solid are packed closely together and vibrate in place. Solids do not flow and are not easily compressed.

Liquid

A liquid is a state of matter that has a definite volume but no definite shape. The particles in a liquid are close together but can move past each other. Liquids can flow and take the shape of their container, but they are not easily compressed.

Gas

A gas is a state of matter that has neither a definite shape nor a definite volume. The particles in a gas are far apart and move freely. Gases can flow and expand to fill their container, and they are easily compressed.

Changes of State

Matter can change from one state to another through processes such as melting, freezing, evaporation, condensation, and sublimation.
