C2: Materials and their Properties

Different materials have different properties so they behave in different ways.

Solid Materials:

Solid materials can differ in many ways. They could each have a different melting point, stiffness, hardness and density along with a different strength in tension (when pulled) as well as a different strength in compression (when pushed).

Suitability:

The suitability of a material to a particular job depends on its properties. For example, a washing-up bowl may be made from the plastic polythene because this material is waterproof and can be melted and reformed into the desired shape. On the other hand, a bicycle tyre is made from rubber because it needs to be…
