A 24.6 g sample of brass is heated in a flask to 125°C in boiling water under pressure, and then is carefully added to a coffee cup calorimeter containing 75.0 g of water. The water temperature changes from 19.5 °C to 29.14 °C. What is the specific heat capacity of the brass? (Note: all heat given off is gained only by the water)

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.
