A rigid insulated container has two rooms separated by a membrane. Room A contains 1 kg air at 200oC and room B has 1.5 kg air at 20oC, both rooms at 100 kPa. Consider two different cases
1) Heat transfer between A and B creates a final uniform T.
2) The membrane breaks and the air comes to a uniform state. For both cases find the final temperature. Are the two processes reversible and different? Explain.
