As we learned in class if a material’s crystal structure is known a theoretical density, can be computed from a tiny fundamental unit using the formula = iron has a bcc crystal structure, an atomic radius of 0.124 nm, and an atomic weight of 55.85 g/mol. compute and compare its theoretical density with its experimentally measured density of 7.87 g/cm^3.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
