A 25.39 g sample of metal is heated to 98.6°C in a hot water bath until thermal equilibrium is reached. The metal is quickly transferred to 50.0 mL (50.0 g) of water at 22.2°C contained in a calorimeter. The thermal equilibrium temperature of the metal sample plus water mixture is 28.3°C.Water has a greater specific heat capacity because the temperature of the water only changed by 5.06 °C, unlike the copper's change of 54.94 °C. The water resisted temperature change more than the copper. 1. Predict: In the Gizmo warm-up, you saw how 200 g of 90 °C copper transfers heat to 200 g of 30.0 °C water.
