A 281 g silver figure of a polar bear is dropped into the 219 g aluminum cup of a well‑insulated calorimeter containing 269 g of liquid water at 21.3∘C. The bear's initial temperature is 99.5∘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).

An insulated aluminum calorimeter vessel of 150 g mass contains 300 g of liquid nitrogen boiling at 77 K. A metal block at an initial temperature of 303 K is dropped into the liquid nitrogen. It boils away 15.8 g of nitrogen in reaching thermal equilibrium. The block is then withdrawn from the nitrogen and quickly transferred to a second insulated copper calorimeter vessel of 200 g mass containing 500 g of water at 30.1 degrees celsius. The block coolds...
