Materials and their Properties
All materials are made up of particles.
All materials exist as a solid, liquid or gas.
The particles in solids, liquids and gases are all arranged in different ways.
When materials are heated or cooled they can change their properties. Some materials are natural and some materials are made.
Properties of Solids:
-Solids are easily controlled.
-Solids can be cut.
-Solids have definite volumes and definite shapes.
-Solids cannot flow.
-Solids cannot easily be compressed.
Solids – The particles in a solid are packed so closely together and therefore hold onto each other very tightly that they can barely move at all. The particles in a solid are fixed in a pattern so the shape and volume cannot be changed unless chopped, cut or chiselled. Therefore, solids don’t flow and why they keep their shape. Solids cannot be squashed into smaller volumes due to the particles being so close together.
A burning candle is a solid, liquid and gas.
