Energy Forms and Changes ( T Brick Iron Energy Symbols Link Heaters Heat Heat Olive Oil Water Cool Cool Intro Systems PHET The heat capacity of brick is about twice as large as iron. The density of iron is more than twice the density of brick. Therefore, the mass of the iron will be greater than twice the mass of the brick. Based on this information, what should happen when you transfer heat into both the brick and the iron? Explain your reasoning.
