You have three blocks of different materials at various temperatures. they are 2-kg block of iron at 600 K, a 3-kg block of copper at 800 K, and a 10-kg block of granite at 300 . The heat capacities are .460(iron), .385(copper), and .790(granite) in kJ/(kg K), all independent of temperature. For solids, the heat capacities at constant pressure and constant volume can be assumed to be equal. What is the maximum amount of work that can be extracted from heat interactions between these blocks? No heat interactions with the environment are allowed. You do not need to describe the details of the process that produces the maximum work, but you do need to describe the final state of the blocks fully.
