What is Absorption? – Meaning and Definition
Definition:
Absorption is the process by which one substance takes in or assimilates another. It commonly refers to how liquids, gases, or energy are soaked up or taken in by another material or system.
Scientific Definition (Physics/Chemistry/Biology):
Absorption is the process in which atoms, molecules, or ions enter into the bulk phase of another substance (solid, liquid, or gas), rather than remaining on the surface.
General Meaning:
-
The act or process of absorbing something (like light, heat, fluid, knowledge).
-
It also means mental immersion – e.g., “His absorption in the book was complete.”
Types of Absorption (With Examples):
| Type | Description | Example |
|---|---|---|
| Physical Absorption | A substance is taken in without chemical change. | CO₂ dissolving in water. |
| Chemical Absorption | A chemical reaction occurs while absorbing. | Ammonia absorbed in acid. |
| Biological Absorption | Nutrients are taken into the body. | Glucose absorbed in the small intestine. |
| Radiation Absorption | Energy absorbed from electromagnetic waves. | Skin absorbing UV rays from sunlight. |
Key Differences:
-
Absorption vs. Adsorption:
➤ Absorption = substance enters into the bulk
➤ Adsorption = substance sticks onto the surface

-

-
The body needs calcium absorption for strong bones.
