aluminium is a reactive metal then also used in cooking why?

Posted by Ramkumar Kundu 4 years, 2 months ago

Mayank Jalandhary 4 years, 1 month ago

This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide. This oxide layer is very stable and prevents further reaction of aluminium with oxygen. Also, it is light in weight and a good conductor of heat. Hence, it is used to make cooking utensils.
