(a) Aluminium foils are used to wrap food items because aluminium metal is malleable. Therefore, it can be beaten into thin foils. (b) Metals are good conductors of heat and electricity. Therefore, immersion rods for heating liquids are made of metallic substances.

Why aluminium is not good for cooking?
Aluminium conducts heat quickly and is quite sturdy which is why it is widely used by people. However, when heated up, aluminium can react with acidic foods like tomatoes and vinegar. This reaction can make the food toxic and might also lead to stomach troubles and nausea.
Why does aluminum foil keep things cold?
Aluminum foil forms a reflective surface, which impedes the transfer of heat from the surrounding atmosphere. Unless your food or beverage is sitting directly on a hot surface — and it shouldn’t be — aluminum is the better choice.
Why Mohan’s mother uses aluminium foil to wrap his food in his lunch box?
(a) Aluminium is malleable, soft and does not react with food items, so it is used to wrap food items. (b) Metals are good conductor of heat and electricity, so immersion rods are made up of metallic substances.
