1. Using solubility data of a gas in a solid, explain how you would determine the molar concentration of the gas in the solid at the solid-gas interface at a specified temperature.
2. Using the Henry's constant data for a gas dissolved in a liquid, explain how you would determine the mole fraction of the gas dissolved in the liquid at the interface at a specified temperature.
3. Air at 70°F and 100 psia is blown through a porous media which is saturated with liquid water at 70°F. Determine the maximum partial pressure of the water evaporated into the air as it emerges from the porous media.
