- - - - Thermal insulators: Do not conduct heat well ( wool, wood, paper...)
- - - - SHAPE
        
        We can CUT, BEND, BREAK or MELT IT.
      - POSITION
        
        It can move to a different place without changes it properties.

- - - - We cannot see the individual substances (salt water)
    - - We can see the individual substances (salad, pizza)
- - - - MAGNETIC SEPARATION : can separate heterogeneous solid mixtures for recycling
        
        DECANTATION: This method uses gravity to separate a mixture of a liquid and a solid, or a mixture of two liquids.
        
        DISTILLATION:To separate a pure liquid from a mixture of liquids
