At least one of the answers above is NOT correct 1 of the questions remains unanswered. (4 points) Air in a rigid tank is initially at 315K and 110kPa. Heat is added until the final pressure is 453kPa What is the change in entropy of the air? Do NOT assume constant specific heats. kgKkJ If the source of the heat transferred into the tank comes from a furnace maintained at 1350K, what is the entropy generation for this process? kgKkJ Note: You can earn partial credit on this problem.
