The drawing shows a container that is partially filled with 2.0 grams of water. The temperature is maintained at a constant 20 °C. The space above the liquid contains air that is completely saturated with water vapor. A tube of length 0.15 m and cross-sectional area 3.0 Ã 10-4 m2 connects the water vapor at one end to air that remains completely dry at the other end. The diffusion constant for water vapor in air is 2.4 Ã 10-5 m2/s. How long does it take for the water in the container to evaporate completely?
