A mass of 5kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 125kPa. Initially, 2kg of the water is in the liquid phase and the rest is in the vapor phase, which is resting ona set of stops, starting moving when the pressure inside reaches 300kPa. Heat transfer continues until the total volume increases by 20%. Why is the last heating process an isobar?
