Difference, Examples & Quiz

What's the difference? Which one is correct?

Absorb

Definition: To take in or soak up (liquid, light, or heat) by chemical or physical action.

Usage: Absorb can be used to describe the process of a material taking in a liquid or substance. It can also refer to the act of understanding or comprehending information.

Example sentences:
  • 1. The sponge absorbed all the water from the spill.
  • 2. She absorbed the knowledge from the book.
  • 3. The black shirt absorbed the sunlight and became hot.
Adsorb

Definition: To accumulate on a surface or in a material through the process of adsorption.

Usage: Adsorb is used to describe the process of molecules or particles sticking to the surface of a material. It is commonly used in chemistry and physics.

Example sentences:
  • 1. The activated carbon adsorbed the pollutants from the air.
  • 2. The silica gel adsorbed the moisture from the container.
  • 3. The charcoal adsorbed the toxins from the water.

"Absorb" and "Adsorb" are two words that are often confused due to their similar spelling and pronunciation. However, they have different meanings and usage. "Absorb" refers to the process of taking in or soaking up a substance, such as a liquid being absorbed by a sponge. On the other hand, "Adsorb" refers to the process of molecules or particles adhering to the surface of a solid or liquid. For example, when a gas is adsorbed onto the surface of a material. It's important to note that the key difference lies in the nature of the substance being taken in or adhered to, with "absorb" involving the entire substance and "adsorb" involving the surface of a material.
