A 291 g silver figure of a polar bear is dropped into the 211 g aluminum cup of a well‑insulated calorimeter containing 273 g of liquid water at 23.1∘C. The bear's initial temperature is 97.3∘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).

A student heats 64.73 g silver to 97.71 °C and carefully lowers it into a cup containing 78.69 g water at 23.26 °C. She measures the final temperature to be 26.46 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.76 J/°C. Assuming that there is no heating of the surroundings calculate the specific heat capacity of silver.
