Solids have a definite shape and volume. Liquids take the shape of the container they are in. Gases have neither a definite shape nor volume.
Solids, Liquids and Gases

Solid: A solid is a state of matter where the particles are closely packed together and held in a fixed position, allowing it to maintain its shape. Liquid: A liquid is a state of matter where the particles are held together but can still move around each other, allowing it to take the shape of its container. Gas: A gas is a state of matter where the particles are spread out and free to move around each other, allowing it to expand to fill its container.

The particles in a gas move faster than the particles in a liquid, which move faster than the particles in a solid. When a gas turns into a liquid, it is called condensation. When a liquid turns into a gas, it is called evaporation. Most of the Earth’s atmosphere is composed of two gases: nitrogen and oxygen.

When matter changes from one phase to another, its physical properties can change dramatically. Gases can be compressed into liquids, and solids can be melted to become liquids. Changes of phase are often accompanied by changes in temperature, pressure, and volume.
