1) A sample consisting of 1.00 mol of an ideal gas at 27 °C is expanded reversibly and isothermally from an initial pressure of 3.00 atm to a final pressure of 1.00 atm. a. Draw a picture showing this process. Identify the system and surroundings. If you were to run this experiment in the lab, how might you ensure this expansion was isothermal (equipment, etc.)? b. Determine AU for this process. c. Find w for this process. Is the system doing work or is work being done on it? d. Find q for this process. Is the system giving off heat or taking it up? What about the surroundings? e. Given the heat flow between the system and the surroundings, what should the sign of AS surr be? For AS? f. Find ASTOT for this process. g. Determine AS and AS surr- h. What is AA for this process (e.g. for the system)? 1) A sample consisting of 1.00 mol of an ideal gas at 27 °C is expanded reversibly and isothermally from an initial pressure of 3.00 atm to a final pressure of 1.00 atm. a.
