Why is it unwise to stir a pot of soup with a metal spoon?

As we stir the pot of soup by a metal spoon which is a conductor, it conducts the heat and starts heating after some time the temperature of the spoon rises and we are not able to hold the spoon and we get burns.

To prevent the soup from cooling soon and prevent our hands from high temperature of the spoon by the contact of soup.

Explanation:

It is unwise to stir a pot of soup with a metal spoon because the metal has a much lower specific heat capacity than that of water i. e. it requires lesser heat energy to raise its temperature. Soup being a blend of edible fats and vegetables forms a layer of fat and starch on the surface preventing much of the heat from escaping to the environment and thus delaying the process of loosing the heat to the ambiance. When a spoon is put into soup it becomes an accessible good conductor path for the heat to escape easily as a result it also increases the temperature of spoon significantly due to its low specific heat capacity.
