2. Saturated liquid water at 250 kPa is contained in a piston-cylinder device as shown in the figure below. The total initial volume is 0.012m'. As the water is heated, the pressure inside the cylinder remains constant until the piston hits the stops. When the piston hits the stops the specific volume is 0.47443 m/kg. Heat transfer to the water continues until the pressure doubles. NOTE: If needed use the closest value in tables 3 to avoid interpolation. Use 5 decimal digits when using specific volume. a.)
