Problem

Two samples are placed in thermal contact inside an insulated box: Sample X is 50 g of copper at 120 °C (cCu=0.39 J g−1 ∘C−1c_{\text{Cu}} = 0.39\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}) and Sample Y is 200 g of water at 25 °C (cH2O=4.18 J g−1 ∘C−1c_{\text{H}_2\text{O}} = 4.18\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}). Without performing a detailed calculation of the final temperature, determine which sample experiences the larger magnitude temperature change by the time equilibrium is reached and briefly justify your answer.
