A copper cylinder whose mass is mcopper = 71.3 grams at 180 C is dropped in a container with my = 25.9 grams of water at 20 C. What is the final equilibrium temperature of the mixture? Assume that no heat is transferred to the container. Please round your answer to one decimal place.A cube of aluminum has an edge length L = 11 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 = 114,505 J, what is increase of the temperature, 47, of the cube? Please round your answer to one decimal place.An ideal gas undergoes an isothermal process starting with a pressure of 4.0 x 10" Pa and a volume of 4.5 cm".
