Description: Absorption is the process by which a substance, typically in liquid or gaseous form, is incorporated into another substance, which can be solid or liquid. This phenomenon is based on molecular interactions and may involve the transfer of energy. In chemical terms, absorption differs from adsorption, as in the former, the absorbed substance penetrates the volume of the absorbing substance, while in the latter, the substance adheres to the surface. Absorption is a fundamental process in various disciplines, including chemistry, biology, and engineering, and is crucial for understanding phenomena such as filtration, purification, and compound separation. Additionally, absorption can be influenced by factors such as temperature, pressure, and the concentration of the substances involved. This process is essential in industrial, environmental, and biological applications, where a substance’s ability to absorb another can determine the effectiveness of systems or processes.
