Question #3 (10 marks) 0.25kg of air in a frictionless piston cylinder at 100kPa and 700K is cooled to a final temperature of 22C by heat rejection to the surroundings which are at a temperature of 22C. 1. Show the process on a P-v diagram with lines of constant temperature, and on a T-s diagram with lines of constant pressure. 2. Determine the total work done and the total heat transfer for the process. 3. Calculate the entropy change for the air, for the surroundings, and the total entropy generated. 4. Does this process violate the 2nd Law? Explain your answer.
