Question

The cans used for soft drinks are made of aluminium.
(a) Give two reasons why aluminium is a good material for this purpose.
(b) Explain why it is important to recycle these cans.

Answer 1

(a) The cans used for soft drinks are made of aluminium because of the following reasons:
(i) Aluminium is light weight, strong and highly corrosion resistant.
(ii) Aluminium cans are recyclable.

(b) It is very important to recycle these aluminium cans as they cause waste disposal problems. Also, aluminium is non-biodegradable. As the strength or quality of the metal is not affected by recycling, we can recycle it as many times as we want. This saves our limited and precious natural resources.
