The word "deliquescences" refers to the process in which a substance absorbs moisture from the atmosphere until it dissolves into a solution. Its antonyms are words that denote the opposite meaning, such as dryness, solidification, and freeze-drying. These words would apply to substances that do not dissolve in water or other solvents, but instead form a solid mass or remain in a powdery state. In chemistry, antonyms for deliquescences could include desiccation, dehydration, or sublimation, all of which involve removing moisture from a substance rather than adding it. Understanding these antonyms can help clarify the differences between different types of chemical reactions and physical behaviors of matter.
