Reasoning: Energy is conserved. absorbed by the iron. Details of the calculation: The melting point of lead is 327.3o C. Assume the final temperature of the system is T. released by the lead as it solidifies is WebPart of the answer is that less dense materials conduct less heat, and thus slow down heat transfer. If you think about using a metal vs wooden spoon in a hot pan of water, it's the metal one that will burn you, because it is more dense and a better conductor of heat. So the transfer of heat from water to air is slowed down by the layer of ice. first united methodist church pine mountain
