Absorção

Absorção refers to the process by which a substance, such as energy, matter, or radiation, penetrates and becomes a part of a physical system, often resulting in a change of state or property. This phenomenon occurs when a substance is exposed to a suitable environment, allowing it to be consumed or taken in by the surrounding system.

In physics, absorption can refer to the absorption of electromagnetic radiation by a material, such as light or radio waves. This process involves the transfer of energy from the radiation to the material, resulting in a change in the material's state or property. In some cases, absorption can lead to a loss of energy, while in others, it can result in the emission of new radiation.

In chemistry, absorption can refer to the process by which a substance, such as a gas or liquid, is taken in by a solid material. This can occur through various mechanisms, including adsorption, where the substance is held on the surface of the material, and absorption, where the substance is taken in and dissolved within the material.

In biology, absorption can refer to the process by which an organism takes in and processes nutrients and other substances from its environment. This can occur through various mechanisms, including the ingestion of food and water, and the absorption of oxygen and other gases through the respiratory system.

Overall, absorption plays a critical role in many natural and industrial processes, and is an important aspect of various scientific disciplines, including physics, chemistry, and biology.
