Question

7 (a) Figure 10 shows information about a glass, a ceramic, a polymer and a metal.

|                  |  glass  | ceramic | polymer | metal  |
|------------------|---------|---------|---------|--------|
| flexibility      |  low    |   low   |  high   |  low   |
| hardness         | medium  | medium  |   low   |  low   |
| reaction with water | no reaction | no reaction | no reaction | very slow reaction |
| electrical conductivity | low | low | low | high |
| melting point    | high    | high    | medium*  | high   |

*polymers soften, rather than melt, when heated.
