Answer 1

The absorption of water through a compound without dissolving in it is known as Hygroscopy

Answer 2

The absorption of water through a compound without dissolving in it is known as Hygroscopy.

• A substance that absorbs moisture from the air but not necessarily to the point of dissolution is called hygroscopic.
• Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption or adsorption from the surrounding environment, which is usually at normal or room temperature.
• If water molecules become suspended among the substance's molecules, adsorbing substances can become physically changed, e.g., changing in volume, boiling point, viscosity, or some other physical characteristic or property of the substance.
• Deliquescence, the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. A substance that absorbs moisture from the air but not necessarily to the point of dissolution is called hygroscopic.
