Task id16214

In a cylinder with a volume V0 = 10 l under the piston there is moist air at a temperature t = 20°C and a relative humidity f = 70%. The volume of the cylinder at the same temperature was reduced by n = 10 times so that drops of liquid appeared on the walls of the vessel. What is the pressure in the cylinder if the initial pressure P0 = 100 mm. Hg? The saturation vapor pressure at temperature t0 is pH = 18 mm Hg. Art.
