Explanation:
Detailed explanation-1: -You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer because of CONDUCTION.
Detailed explanation-2: -Metal is a good conductor of heat. If the handles of the saucepans were made of metal, they would become too hot to hold and that would be dangerous. Someone trying to hold a metal handle could drop the saucepan or receive a nasty burn.
Detailed explanation-3: -The heat moves through the spoon because the spoon is colder than the soup and because the spoon is in direct contact with the hotter soup. This type of heat transfer is known as conduction.
