Substances that exhibit hygroscopicity are known as hygroscopic materials.
The degree of hygroscopicity varies significantly among different substances. Some materials, like anhydrous salts such as
The phenomenon of hygroscopicity is influenced by factors such as the substance's chemical composition, its surface
