ADHESION Meaning and
Definition
-
Adhesion is a noun that refers to the action or process of sticking or attaching one thing to another. It is the force of attraction or molecular attraction between the surfaces of different materials that causes them to cling together. This characteristic allows substances to stick together or bind to surfaces.
In a physical context, adhesion can occur between solids, liquids, or gases. For example, adhesion may involve the sticking of water droplets to a glass surface due to attractive forces between the water molecules and the glass. In this case, the water acts as the adhesive, while the glass is the substrate.
Adhesion also plays a crucial role in biology, as it enables the attachment of cells to one another or to other surfaces within an organism. This property is fundamental in various biological processes, such as wound healing, cellular migration, and embryonic development.
In manufacturing and engineering fields, adhesion is of great importance. It influences various processes, including painting, adhesive bonding, and the performance of coatings. For instance, strong adhesion is desired when applying a coat of paint to ensure it adheres to the surface and lasts for an extended period.
In summary, adhesion refers to the act or state of sticking or attaching one substance to another, either through physical forces or chemical interactions. It is a fundamental property in various natural and synthetic processes and is essential for multiple fields of study, including physics, chemistry, biology, and engineering.
