The value of specific heat for copper is 390 J/kg⋅°C, for aluminun is 900 J/kg⋅°C, and for water is 4186 J/kg⋅°C. What will be the equilibrium temperature when a 265 g block of copper at 235°C is placed in a 135g aluminum calorimeter cup containing 865 g of water at 14.0°C? Express your answer using three significant figures.
