A small pipe with a valve connects two rigid tanks, as shown in the sketch. The volume of tank A is 0.6m³ and it initially contains 0.03m³ of liquid water and 0.57m³ of water vapor in equilibrium at 480 K. Tank B is initially completely evacuated. After the valve is opened, the tanks eventually come to the same pressure of 0.7MPa. During the process, enough heat transfer occurs that the final temperature is still 480 K. Determine the volume (m³) of tank B.
