Answer: D. The equilibrium moisture content of the solid can be reduced by increasing the absolute
Explanation
Equilibrium moisture content depends primarily on relative humidity and temperature conditions. Absolute humidity alone does not dictate the equilibrium moisture content of solids. Changes in air temperature alter moisture holding capacity and shift equilibrium values. Drying processes remove moisture until the solid reaches equilibrium with surrounding air. Relative humidity represents the ratio of partial pressure to saturation vapor pressure. Packed towers operate efficiently when gas velocity remains below flooding limits.
Food and pharmaceutical storage requires precise humidity control to prevent spoilage. Engineers use psychrometric charts to analyze drying and humidification operations accurately. Understanding moisture equilibrium helps determine the drying time required for materials. Changes in barometric pressure generally have negligible effect on relative humidity calculations. Operating velocity in packed towers is indeed maintained around half of flooding velocity. Elution correctly describes the desorption of adsorbed solutes using a suitable solvent.
