Steel swords are made by heating metal, moulding it, and then plunging it into water in a process known as quenching. This quenching fluid tends to be oil as quenching in water can cause cracks. If you were making a sword and the steel blade was 1.2 kg and at 1200C when it comes out of the forge, and you plunged it in a 50L tank of oil (at 22C) to quench the blade, what would be the final temperature of the sword and the oil?
