| Solids cannot be squashed into a smaller size. You can change their shape by squashing, but their size stays the same. |
Examples of solid materials:
- Brick
- Wood
- Plastic
- Glass
- Ice

| Liquids cannot be squashed into a smaller size. You can change their shape, but their size stays the same. |
Examples of liquid materials:
- Water
- Oil
