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...
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...

Problems 4, 5 & 6
15) A heat-conducting rod, 0.90 m long and wrapped in insulation, is made of an aluminum section that is 0.20 m long and a copper section that is 0.20m long. Both sections have a cross- sectional area of 0.00040 m2, The aluminum end and the copper end are maintained at temperatures of 30 C and 230 C respectively. The thermal conductivities of aluminum and copper are 205 W/m K (aluminum) and 385 W/m K (copper)....
