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

1. Good thermal conductivity
2. Good electrical conductivity
3. Ductility
4.  High melting point

Options

• (i) and (ii)

• (i) and (iii)

• (ii) and (iii)

• (i) and (iv)

Answer 1

(i) and (iv)

Explanation - 

Aluminium is used for making cooking utensils because it is a good conductor of heat and has a high melting point of about 660 °C. So, when on top of a stove the aluminium vessel would not melt while cooking.
