In the heat-insulated cylinder under the weightless piston there is m1 = 1 g of saturated water vapor. External pressure is normal. Into the cylinder, m2 = 1 g of water was introduced at a temperature of T2 = 295 K. Neglecting the cylinder´s heat capacity and friction, find the work of the atmospheric pressure forces when the piston is lowered. Steam is considered an ideal gas. The molar mass of water is 0.018 kg / mol, the specific heat of water vaporization is q = 2.26 * 106 J / kg, the specific heat capacity of water is court = 4200 J / (kg * K).
