Problem

A 200 g aluminum block at 150 °C is quickly placed into 500 g of water at 20 °C inside an insulated container. Assuming no heat is lost to the surroundings and using specific heat capacities of cAl=0.90 J g−1 ∘C−1c_{\text{Al}} = 0.90\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1} and cH2O=4.18 J g−1 ∘C−1c_{\text{H}_2\text{O}} = 4.18\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}, calculate the final equilibrium temperature of the system.
