Usually in paper 2, especially in essay section B/C, the question will provide you with a table of comparison. For eample, if the question ask you to choose a material from a table to build an electric kettle..then you are asked to choose the most suitable characteristic. For example,
| Kettle | The characteristics of the material used in the heating elements in the kettle | |
| | Boiling point/°C | Resistivity / 10 |
| W | 3501 | 13.5 |
| X | 1085 | 5.2 |
| Suitable Characteristic | Reason |
| High Boiling Point (1 mark) | Not easily melt (1 mark) |
| High Resistivity (1 mark) | It can produce more heat ( 1 mark) |
e.g:
kettle W is most suitable because it has high boiling point & high resistivity.
If you answer in table form, you are more focused & will go straight to the point
