Deliquescence is the process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution. Deliquescence occurs when the vapour pressure of the solution that is formed is less than the partial pressure of water vapour in the air.

Osmosis is the diffusion of the movement of water from a region of higher concentration to a region of lower concentration through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion (passive transport).

Definition: the process in which a soluble substance picks up water vapor from the air to fom a solution. In order for deliquescence to occur, the vapor pressure of the water in the air must be greater than the vapor pressure of the saturated solution.

Desiccation is the state of extreme dryness, or the process of extreme drying. A desiccant is a hygroscopic (attracts and holds water) substance that induces or sustains such a state in its local vicinity in a moderately sealed container.

@Ranjit.
Liquefaction is a term used in materials sciences to refer to any process which either generates a liquid from a solid or a gas, or generates a non-liquid phase which behaves in accordance with fluid dynamics.

Deliquescent materials are substances (mostly salts)that have strong affinity for moisture and will absorb relatively large amounts of water from the atmosphere if exposed to it, forming liquid solution.

Tending to melt or dissolve; especially tending to undergo gradual dissolution and liquefaction by the attraction and absorption of moisture from the air.

Certain compound when exposed to the atmosphere loose their water of crystallization and turn into a powder.
For example iron chloride.
For example iron chloride.

Efflorescence means loss of water of crystallization from hydrated or solvated salts to the atmosphere on exposure to air
