A piston cylinder, like the one shown in the figure, is filled with a saturated mix of water (2 kg is vapor, 1 kg is liquid). The pressure is measured

to be 0.16 MPa. The mass of the piston is such that a pressure of 0.5 MPa is required for the piston to start floating up. The water is then heated until the volume is 20% greater than the initial volume. A. Determine the final temperature: B. Calculate the boundary work: C. Sketch a P-V diagram of this process. Make sure to indicate the saturation lines and the constant temperature lines
