Problem

Equal masses of iron (cFe=0.45 J g−1 ∘ ⁣C−1c_{\text{Fe}} = 0.45\,\text{J\,g}^{-1}\,^{\circ}\!\text{C}^{-1}) and aluminum (cAl=0.90 J g−1 ∘ ⁣C−1c_{\text{Al}} = 0.90\,\text{J\,g}^{-1}\,^{\circ}\!\text{C}^{-1}) each absorb 100 J of thermal energy. Which metal undergoes the larger temperature change, and why?
