WebIn the equation, you only need to put the change in degrees C or the change in degrees K not the actual temperature itself. A change of 1c is the same as a change of 1K … 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 …
