Question

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

• A. Good thermal conductivity
• B. Poor electrical conductivity
• C. Resistant to corrosion
• D. High melting point

Answer 1

Answer: (A), (C), (D)

The correct options are
A Good thermal conductivity
C Resistant to corrosion
D High melting point

• For cooking utensils, the materials should be able to transfer heat, to cook food. They should be able to withstand high heat and should not corrode.
• Aluminium has a good thermal conductivity, a high melting point and it is resistant to corrosion.
• It reacts with oxygen to form a protective layer on its surface which prevents the corrosion of metal.

Hence, because of these properties aluminium is used to make cooking utensils.
