One kilogram of water is contained in a piston-cylinder device at 100 degC. The piston rests on lower stops such that the volume occupied by the water is 0.835 m3. The cylinder is fitted with an upper set of stops. When the piston rests against the upper stops, the volume enclosed by the piston-cylinder device is 0.841 m3. A pressure of 200 kPa is required to support the piston. Heat is added to the water until the water exists as a saturated vapor. Find the final specific volume (v4 = vg). Please show steps for interpolation.
