You drop a 295-g silver figure of a polar bear into the 203-g aluminum cup of a well-insulated calorimeter containing 273 g of liquid water at 21.1 degree C. The bear's initial temperature is 96.1 degree C. What is the final temperature of the water, cup, and bear when they reach thermal equilibrium? The specific heats of silver, aluminum, and liquid water are, respectively, 234 J/(kg middot K), 910 J/(kg middot K), and 4190 J/(kg middot K).
