At noon a batch of molten iron at a temperature of 1500 degrees Kelvin is removed from a furnace to a room whose temperature is held at 300 degrees Kelvin. After twenty minutes the iron has cooled to 1100 degrees Kelvin. The iron will be subject to further processing when its temperature is 500 degrees Kelvin. When will that be? Explain.
