1. (Tinoco 3.1) One mole of an ideal monatomic gas is expanded from an initial state at 3 bar and 450 K to a final state at 2 bar and 350 K. a) Construct a thermodynamic cycle for this process by combining two different paths, 1) an isothermal expansion and 2) cooling at constant pressure, that connect the same initial and final state of the original expansion. Specify the paths, and calculate the work (w) and heat (q) for each path. b) Calculate AU and AS for each path. What is the total energy and entropy change for the original process?
