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?
Perhaps he should dump it in water first, to make use of its high specific heat and heat of vaporization, and then when all the water has boiled away, use the oil.
