We can explain the differences between solids, liquids and gases by knowing what they are made of.
Scientists have found out that all materials are made of very tiny particles. These particles are so small that we cannot see them with our eyes, or even with a microscope!
The position and behaviour ofthe particles is different insolids, liquids and gases.

GASES
Materials in a gaseous state can spread out tocompletely fill the container or room they are in.
Gases have weight.
Gases can be squashed.
Gases do not keep their shape.

Carbon dioxide is a gas that is all around us. It makes up only about 0.04% of the Earth’s atmosphere, but it can be very useful.
Some fire extinguishers use carbondioxide to cool flame and to stop oxygen getting to the fire.
Carbon dioxide freezes at -78°C, and it becomes a solid called dry ice. It is used to transport food that needs to be keptcool and fresh, such as on aeroplanesand trains.
And as you have heard, carbon dioxide is dissolved in water to create fizzy drinks.
