Aluminium is used for making cooking utensils. Which of the following properties of aluminium are responsible for the same?
(A) Good thermal conductivity
(B) Good electrical conductivity
(C) Ductility
(D) High melting point

Explanation

Solution

Aluminium is a silvery-white metal that is highly malleable and ductile. It is the second most malleable metal and sixth most ductile metal. It is a very light-weight metal as well and thus, it finds its usage in different applications.

Complete step by step solution:
Aluminium is used in a huge variety of products including, cars, foils, kitchen utensils, kitchen cabinets, aircraft bodies, wires, etc. This is mainly due to some of its properties such as low density, non-toxic nature, and thermal conductivity, has excellent carrion resistance, and can be easily cast, machined, and formed. It is also non-magnetic and non-sparking. Hence the reason that aluminium is used for making cooking utensils is that it is Ductile.
Thus, the correct option is C.

Notes:
Aluminium is often used as an alloy as it is itself not much strong and its alloys with copper, manganese, magnesium, and silicon are both lightweight as well as strong. Aluminium is a good conductor of electricity and hence used to make electrical wires as it is cheaper than copper and the weight for weight is almost twice as good as the copper conductor. It is also non-magnetic and non-sparking. But with so many advantages there are also some disadvantages associated with the usage of aluminium. Alumina is toxic to the plants as well as to the human bodies beyond a certain limit but cooking in aluminium utensils does not increase its amount too much in our diet unless acidic foods are cooked in it.
