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. WebExperiments show that the heat transferred to or from a substance depends on three factors—the change in the substance’s temperature, the mass of the substance, and …
