What is the 3 state of matter?

There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.

Solids ...

Solids have a fixed shape and fixed volume, which means they don't move to fill a container when they're placed in it. They hold their own shape and volume. Solids cannot be compressed into a smaller space very easily. There's not much space between the atoms. Most solids change their shape if they are squeezed or pulled with enough force. The particles in the solid cannot move closer together, but they can often slide around and past each other if they are pushed hard enough. Thin bars and sheets of solids can often be bent or moulded.

Liquids ...

The atoms in a liquid are free to move around, although they cannot move closer together or further apart. This means a liquid flows and changes shape to fill the space around it. It takes on the shape of whatever container it is in. If it is poured out of its container, a liquid will form a puddle. Liquids do not have definite shapes; they take the shape of the container but have a definite volume. The particles of liquids are loosely packed than the particles in solids. They can be compressed to a small extent.

Gases ...

A gas is a substance that has no fixed size or shape. When inside a closed container, a gas will expand to fill the container. An example of gas is the air you breathe. The gas inside your digestive tract is made of air and other gases. Fire is formed from a combination of hot gases. Natural gases are lighter than air. Gases that are usually liquids at room temperature are called “vapor.” “Water vapor” is something you've probably heard of before. Some gas particles move so fast that they travel faster than the speed of sound!
