Solids Liquids and Gases
All materials can be put into one of three categories or states:
1.Solids – the shape of a solid does not change on its own – it is rigid. They also have a fixed volume.
2. Liquids – the shape of a liquid does change, it is not rigid. It fits the shape of the container it is put in. Liquids flow. They also have a fixed volume.
3. Gases – gases do not have a shape, they completely fill any container they are put into. They do not have a fixed volume but the same volume as the container.
Materials can change from one of these states to another. Use the PowerPoint to find out more…
