How could you find out which material is the best conductor of heat using a metal spoon a wooden spoon and a piece of aluminium foil a bowl of hot water and some butter and a knife?

To determine the best conductor of heat among a metal spoon, wooden spoon, and aluminum foil, you can perform a simple experiment. Place equal amounts of butter on the ends of each spoon and the aluminum foil, then immerse the other ends in a bowl of hot water. After a few minutes, observe which material causes the butter to melt the most; the one that melts the butter fastest will be the best conductor of heat.
