Dip an aluminum spoon, a copper knuckle, an iron nail and a wooden stick into a glass of hot water

Dip an aluminum spoon, a copper knuckle, an iron nail and a wooden stick into a glass of hot water, which conducts heat better?

The ability to conduct heat is called thermal conductivity, and best of all, of the items listed in the question, a copper coin conducts heat. It is inferior in thermal conductivity to an aluminum spoon. An iron nail, on the other hand, has an even worse thermal conductivity of the listed items. As for the wooden stick, it does not conduct heat at all. This is explained by the fact that molecules in heated water move faster and transfer heat (energy) to slow particles that are in colder objects.
