Question

Why do cooking vessels usually have copper bottoms?

• A. Copper has low melting point.
• B. Copper is an insulator of heat.
• C. Copper is a good conductor of heat.
• D. Copper is cheap.

Answer 1

The correct option is C

Copper is a good conductor of heat.

Cooking vessels usually have copper bottoms because copper, a metal, is a good conductor of heat. But, the whole vessel cannot be made of copper as it will react with the food, hence, only the bottom of the vessel is coated with copper which is the part in contact with flame/heat. Also, copper is more expensive than aluminium.
