Water initially at 300 kPa and 0.5 m^3/kg is contained in a piston-cylinder device fitted with stops so that the water supports the weight of the piston and the force of the atmosphere. The water is heated until it reaches the saturated vapor state and the piston rests against the stops. With the piston against the stops, the water is further heated until the pressure is 600 kPa. On the P-vP−v and T-vT−v diagrams, sketch, with respect to the saturation lines, the process curves passing through both the initial and final states of the water. Label the states on the process as 1, 2 and 3. On both the P-vP−v and T-vT−v diagrams, sketch the isotherms passing through the states and show their values, in ^\circ{} ∘ C, on the isotherms.
