A cylinder with a cross-section of 100 cm² is placed vertically in a vessel from which air is pumped out. The cylinder covers the movable piston, under which there is 100 cm³ of water. The cylinder with a piston and water have a temperature of 100°C. The plunger is released. When it stopped, it turned out that there was ice under it at 0°C and water vapor. The saturated vapor pressure above the ice at 0°C is 610 Pa. The entire system is insulated from the surrounding space. The heat capacity of a cylinder with a piston is 42 J / K. How high did the piston go?
