In essay question paper 2 section B and C, the question will provide you with a table of comparison. For example, if the will question ask you to choose a material from a table to build an electric kettle….then you are asked to choose the most suitable material.
Example:
| Kettle | The characteristics of the materials are used in the heating element in the kettle | |
| Boiling point / 0C | Resistivity / 10-8 Wm | |
| W | 3501 | 13.5 |
| X | 1085 | 5.2 |
To score this section it’s easier if you to answer it by making a table of comparison like this:
| Suitable Characteristic | Reason |
| High Boiling Point (1 mark) | Not easily melt (1 mark) |
| High Resistivity (1 mark) | It can produce more heat ( 1 mark) |
Then you’ll choose which one is the most suitable and repeat its suitable characteristic.
Kettle W is most suitable coz it has high boiling point & high resistivity. [2 marks]
If you answer in table form, you are more focused and will go straight to the point.
Otherwise if you choose to write like typical english essay... there's a tendency for you to repeat the points.
