Steel, plastic and wood are solids at room temperature. Ice is solid water.

The particles in a solid have the following characteristics:

they are arranged in a regular pattern
they are close together
they are held together by strong forces called bonds
they can vibrate in a fixed position
they cannot move from place to place

The table shows some of the properties of solids and why they are like this.
