2. Consider a process in which two tanks A and B are connected by a valve. Tank A, which is insulated, has a volume of 600 liters and contains steam at 1.4 MPa, 300°C. Tank B, which is uninsulated, has a volume of 300 liters and contains steam at 200 kPa, 200°C. The valve connecting the two tanks is now opened and steam flows from A to B until the temperature in A reaches 250°C, at which time the valve...
