Properties of Solids, Liquids, and Gases

All materials are made of tiny particles. These are called atoms. Sometimes atoms join together to form molecules. Scientists talk about different materials by talking about these particles. They talk about how the atoms (or molecules) are arranged. This helps scientists explain solids, liquids, and gases.

Solids

In solids, the particles are arranged in a regular pattern. They are held together by strong forces. This is why solids have a fixed shape. You cannot squash or change the volume of solids. The particles are already as close to each other as they can get.

Ice to Steam This diagram shows the particles in a solid.

Liquids

With liquids, the particles are still very close. But the forces holding them together are not as strong as in solids. The particles can move around. This is why you can pour a liquid. You cannot squash a liquid because the particles are still very close together.

Ice to Steam This diagram shows the particles in a liquid.

Gases

The particles in a gas are a long way apart. They move around very quickly. Gases are easy to squash because there is a lot of space between the particles.

Ice to Steam This diagram shows the particles in a gas.

What Happens When a Material is Heated?

This diagram shows what happens to the particles of a solid material as it is heated.

Well this website doesn't provide quite enough information, But it did give me an Idea on what I should include in my Science booklet. So I think you can include more information. But until then, this will have to do. Thanks :)

good info.Thanks for clear explaination.Here is an interesting Density of solids app i found how to measure
Density of various solids using liquids, In addition it has a quiz at the end to make your learning exciting. here is the link https://play.google.com/store/apps/details?id=com.ajax.densityofsolids
