Project #96340 - physics

1) The density of solid aluminum at 20°C is ρ = 2.70 g/cm3. When it is liquid at 660°C the density of the liquid state is decreased: 2.38 g/cm3. How much work does a block of aluminum of mass 357 kg do if it is heated at p = 1.0 atm from 20°C to 660°C? J 2) 223 g of water at 12°C is contained in an iron container of mass 327 g. An additional 144 g of water at 100°C is added. What is the final equilibrium temperature if we treat the system's water and container as isolated? Use the heat capacity values from the table. table in file °C
