You drop a 289-g silver figure of a polar bear into the 251-g aluminum cup of a well-insulated calorimeter containing 275 g of liquid water at 23.1°C. The bear’s initial temperature is 95.7°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).
