You drop a 291-g silver figure of a polar bear into the 247-g aluminum cup of a well-insulated calorimeter containing 261 g of liquid water at 21.9°C. The bear\'s initial temperature is 97.9°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·K), 910 J/(kg·K), and 4190 J/(kg·K).
