A 293 g silver figure of a polar bear is dropped into the 227 g aluminum cup of a well-insulated calorimeter containing liquid water at 21.5°C. The bear's initial temperature is 96.3 °C. What is the final temperature of the water, cup, and be 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).

Question
A 293 g silver figure of a polar bear is dropped into the 227 g aluminum cup of a well-insulated calorimeter containing 269 g of
liquid water at 21.5 °C. The bear's initial temperature is 96.3 °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).
final temperature:
