tips fizik kertas 2

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 Ωm
W
3501
13.5
X
1085
5.2
just  write down your answer in a table. It is easy and it is simple.
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 choose which one is the most suitable & repeat its suitable characteristic; 
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
