Task id12368

In a cylinder under a weightless piston with area S=100 cm2 there is m1=18 g of saturated water vapor. m2=18g of water is injected into the cylinder at t0=0°C. How much will the piston move? Neglect the heat capacity and thermal conductivity of the cylinder. Outside the cylinder, normal atmospheric pressure p0=105 Pa. Specific heat capacity and heat of vaporization for water c=4.2•103 J/(kgK) and r=2.3•106 J/kg.
