What is Absorption? – Meaning and Definition

Definition:
Absorption is the process by which a substance takes in or assimilates another substance, such as liquids, gases, or nutrients. It commonly occurs in physical, chemical, and biological processes.

Meaning:
The term “absorption” refers to the way one substance is taken in or soaked up by another. It plays a crucial role in various scientific fields, including physics, chemistry, and biology.

Types of Absorption:

1. Physical Absorption:

   • Occurs when molecules are taken in without chemical changes.
   • Example: A sponge absorbing water.

2. Chemical Absorption:

   • Involves a chemical reaction between the absorbed substance and the absorbing material.
   • Example: Carbon dioxide being absorbed by a chemical solvent.

3. Biological Absorption:

   • The process by which cells or organisms take in nutrients or substances.
   • Example: The small intestine absorbing nutrients from food.

Examples of Absorption in Daily Life:

• The skin absorbing lotion.
• Plants absorbing sunlight for photosynthesis.
• A black surface absorbing more heat than a white surface.

Absorption is a fundamental process in nature and technology, influencing everything from digestion to industrial applications.
