how could you find out which material is the best conductor of heat,using a metal spoon,a plastic spoon,a wooden spoon and a piece of aliminium foil,a bowl of hot water and some butter and a knife
Use the knife to cut the butter into equal size chunksPut one chunk in the bowl of each kind of spoonCompletely fill the bowl with Hot waterCut a slot in the foil for the handle of each spoonCover the bowl with aluminum foilPush the handle of the spoons through the foil into the waterObserve the time it takes to for the butter to melt in each spoonSince you're only asked to find the best conductor (and not rank them in order) the answer should be obvious in a relatively short time.
