A cylinder/piston arrangement contains 5 kg of water at 100 degrees celsius with x=20%, and the mass of the piston is 75 kg. The outside pressure is 100 kPa, and the cylinder area is 24.5 cm^2. Heat is now added until the water reaches a saturated vapor state. Find the initial volume, final pressure, work, and heat transfer. Any help would be appreciated, thanks in advance.
