kapillärkrafterna
Kapillärkrafterna, or capillary forces, refer to the phenomenon where a liquid can flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. This occurs due to a combination of cohesive and adhesive forces. Cohesion is the attraction between molecules of the same substance, in this case, the liquid. Adhesion is the attraction between the molecules of the liquid and the molecules of the surface it is in contact with, such as the walls of a narrow tube.
When a liquid like water is in contact with a surface to which it adheres strongly, the
This phenomenon is crucial in many natural and technological processes. In plants, capillary action allows water
