An insulated cylinder is divided into two parts of 1 m3 each by an initially locked piston. Side A has air at 200 kPa, 300 K, and side B has air at 1.0 MPa, 1000 K. The piston is now unlocked so it is free to move, and it conducts heat so the air comes to a uniform temperature TA TB. Find the mass in both A and B, and the final T and P.
