A coffee-cup calorimeter has 44.1 g of water at 23.7 °C. A sample of copper weighing 12.7 g is heated in a boiling water bath to have an initial temperature of 100.0°C. The hot copper is then added to the water in the coffee-cup calorimeter. Given that the specific heat of solid copper is 0.385 J/(g·°C), calculate the final temperature of the water (and the copper) in the calorimeter.
