The number of molecules exchanged between water and its vapor every second at room temperature is about 1021 per 1 cm2 of surface. Let us assume that all molecules leaving the water are immediately removed from its surface, and the temperature of the evaporating water remains unchanged. How long would it take for a glass of water to evaporate at room temperature? (The volume of the glass is 200 m3, and its cross-sectional area is 40 cm2.)
