Explanation:
Solid
Something is usually described as a solid if it can hold its own shape and is hard to compress (squash). The molecules in a solid are closely packed together – they have a high density.
Right now, you are probably sitting on a chair, using a mouse or a keyboard that is resting on a desk – all those things are solids.
Liquid
In liquids, the molecules have the ability to move around and slide past each other. A liquid will take on the shape of the container it is being held in. While a liquid is easier to compress than a solid, it is still quite difficult – imagine trying to compress water in a confined container!
Water is an example of a liquid, and so is milk, juice and the petrol you put in the car.
Gas
In gases, the atoms are much more spread out than in solids or liquids, and the atoms collide randomly with one another. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.
Right now, you are breathing in air – a mixture of gases containing many elements such as oxygen, nitrogen and carbon.
