Question 3
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)
Option (d) is correct.
For cooking utensils, the material should be able to transfer heat to cook food and the utensil should be able to withstand high heat. Aluminium with good thermal conductivity and a high melting point is a suitable fit to make cooking utensils.
