A blacksmith wishes to cool his hot piece of steel as rapidly as possible. He has a bucket of ice-water and a bucket of oil (at room temperature). Which bucket should he dump his steel into?

oil has a higher caloric quoefficient, it will absorb heat more rappidlley, but not much, becose the mass of oil is less than the mass of water, if the bucket is big enough, the answer is oil
