Determine how much the vapor pressure above water droplets with a diameter of 0.2 μm is greater than the vapor pressure above a flat surface at a temperature of 298 K. The surface tension of water is 71.96 mJ / m2, the molar volume of water is 18.05 cm3 / mol. How will this pressure change if the dispersion of the droplets increases 10 and 100 times.
