Aluminium is used for making cooking utensils. Which of the following properties of aluminium are responsible for the same?

(i) Good thermal conductivity (ii) Good electrical conductivity

(iii) Ductility (iv) High melting point

(A) (i) and (ii) 

(B) (i) and (iii)

(C) (ii) and (iii) 

(D) (i) and (iv)

 

Answer

Since aluminium is a good conductor of heat, it can heat up/cook the food.

It has a high melting point i.e. it can withstand high temperatures which are required in cooking

So, the correct answer is (d) (i) and (iv)
