50 grams of iron is heated over a flame for several minutes. It is then plunged into a closed container containing 1.0 litre of cold water, originally at 15 degree Celcius. After the temperatures equalize, the water is now found to be at 17 degree Celcius. If no water changed state to become steam and there were no losses to the surrounding environment, what was the temperature of the iron just prior to being immersed in the water?
