The quantity of heat acquired or lost by a system is given by: M*S*?T Where: M= mass S= Specific heat ?T= change in temperature So if the mass of the wood and metal are the same; and the change in temperature are the same (Taken out of the oven together at the same temperature), then the only thing left is the specific heat. The item with the greatest specific heat, in this case the wood, will give out the most heat and therefore melt more ice. |
