Solids
Steel, plastic and wood are solids at room temperature. Ice is solid water. The particles in a solid are:
- close together
- arranged in a regular way
Particles in a solid
Strong forces, called bonds, attract the particles towards each other. This means that the particles in a solid:
- can vibrate in a fixed position
- cannot move from place to place
The table shows some of the properties of solids and why they are like this:
| Property | Reason |
|---|---|
| They have a fixed shape and cannot flow | The particles cannot move from place to place |
| They cannot be compressed (squashed) | The particles are close together and have no space to move into |
Solids such as concrete are useful for buildings and their foundations because they cannot be compressed.
