A 50-gram copper cylinder at 180 C is dropped in a container with 51.4 grams of water at 20 C. What is the final temperature of the mixture? Assume that no heat is transferred to the container. The specific heats of copper and water are, respectively, 0.390 J/g "C and 4.18 J/g "C.A cube of aluminum has an edge length L = 12.9 cm. Aluminum has a density of 2.7 g/cm and a specific heat of c = 0.91 J/gxC. When the internal energy of the cube increases by Q = 111,471 J, what is increase of the temperature, AT, of the cube? Please round your answer to one decimal place
