9. A 680 g piece of copper is heated in a furnace to a temperature T. The copper is then inserted into a 145 g copper calorimeter containing 280 g of water. The initial temperature of the water and calorimeter is 18 °C, and the final temperature after equilibrium is established is 40 °C. When the calorimeter and its contents are weighed, 37.0 g of water are found to have evaporated. What was the temperature T?(Cw = 4186 J/(kg.°C), L=3.35 x 105 J/kg, Ly=2.26 × 10% J/kg, Ccopper 387 J/(kg.°C) X 462.44 °C B Show my other submissions
