Question

Metal utensils are used for cooking give scientific reason​

Answer 1

Reason:-

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.

Answer 2

Answer:

It is because metals conduct heat very quickly. This is the only reason. To do cooking in less time metals are used. Aluminium is often used as cooking utensils as the coefficient of thermal expansion is very high as well as it conducts more heat. And it's very old custom of using metals as cooking utensils the ancient Indus Valley civilization people used bronze metal as utensils which is an alloy of copper and tin. Because bronze is corrosion resistant. Earthen pots were used in medieval times other than metals which used to give good taste to food cooked in pots. But pots takes so much time to conduct heat and cooking in Earthen pots takes more time and so as time passed the use of Earthen pots lessened and use of metals filled the space.
