Question

The stainless steel vessels in the kitchen have copper coating on the bottom. Write scientific reasons.

Answer 1

To answer this question, you must recall the properties of copper metal and stainless steel. A vessel is required to be made of a material that is a good conductor of heat and is resistant to corrosion. Copper is one of the best conductors of heat and electricity.

Complete answer:
Stainless steel is an alloy and is resistant to stains and its shine is maintained or long. As a result, the majority of kitchen utensils are made up of stainless steel. Some of these utensils may also have a base made up of copper metal. The use of copper coated utensils has certain advantages to it as compared to stainless steel utensils.
There are two main reasons for this. The first reason is the conduction of heat. Copper is a good conductor of heat in comparison to stainless steel. Hence, copper coating on the bottom of the utensil helps in faster conduction of heat. As a result, the food in the utensils is heated faster and is cooked quickly.
The second advantage is the resistance to corrosion. Copper metal does not react with water. Thus, after repeated use for several times, the shape and the durability of the utensil remains intact. But steel contains iron which reacts with water. On prolonged use, the stainless steel vessels get deformed.
Thus, utensils with a copper bottom are preferred.

Note:
Metals have a tendency to react with hot water or steam to form hydroxides. But metals like copper, silver and gold are resistant to this reaction.
