In accord with the second law of thermodynamics which states that heat spontaneously travels from a hotter object to a colder one, when metal touches something hot, the area where it touched something hot, will get warmer because of the increase in energy of the molecules, this warmth will spread throughout all the available metal until the metal and the hot substance it is touching have the same internal energy.
the hot air touches it that's why
because when something hot touches something cold the heat touches the surface of the cold thing making it burn and spread the heat around making it warm.
it cools down
Steel gets stronger
When you hand touches the hot handle of a pot. When you touch an ice cube and it melts in your hand. When the spoon touches hot water and the spoon gets hot. When the spoon touches cold ice cream and the ice cream melts.

the body turn hot
it is conducting the heat away
it reacts by burning where you have touched something
If it is hot it will most likely explode. If it is cold, it might stratch the outer quartz glass, and then when you try and turn it on the glass will shatter because of the scratch.
the metal will become hot
Retracting a hand if it touches something hot
the hot air touches it that's why
because when something hot touches something cold the heat touches the surface of the cold thing making it burn and spread the heat around making it warm.
it cools down
like this: You will detract your hand if it touches something hot. LOL
A reflex action.
