Problem 1. A 35.6 g piece of aluminum metal rod is heated to 89.4 °C and then placed in an insulated container containing 51.2 g of water at 22.3 °C. Assuming no loss of water and a heat capacity of 19.82 J/K for the container, what is the final temperature of the system? You may assume that the container is always at the same temperature as that of the water. (HINT: qmetal + qcontainer + qwater-0) Problem 2. Calculate Δ...
