  1. What are the six terms used to describe a solid?
    • - Brittle
    • - Ductile
    • - Malleable
    • - Hard
    • - Stiff
    • - Tough
  2. What is meant by the term brittle?
    If you apply a force to a brittle material, it WILL NOT deform plastically. However if there is enough force applied it will suddenly snap, they are also quite weak if they have cracks in them. e.g a chocolate bar is a brittle material - Break individual chunks of chocolate without the whole bar changing shape. Also ceramics (glass) shatter.
  3. What is meant by the term ductile?
    • - You can change the shape of ductile materials
    • - They keep their shape when there deformed in this way.
    • - An example of a ductile material is copper
    • - Ideal for electric wires
  4. What is meant by the term malleable?
    • - Their shape can be changed fairly easily e.g hammering or rolling
    • - Malleable materials will not keep their strength
    • - Gold is an exaple of a malleable metal
  5. What is meant by the term hard?
    They are very resistant to cutting, indentation and abrasion

    -
    They can be used as cutting tools often made by harden steel and diamond
  6. What is meant by the term stiff?
    Stiff materials have a high resistance to bending and stretching

    -
    Changing the shapes of stiff materials
