It has been suggested that this article or section be merged into Capillary action. (Discuss)

Capillarity causes the part of the surface of a liquid in contact with a solid, to be either elevated above (e.g. water), or depressed below (e.g. mercury), the rest of the surface. This trait is named for the behaviour of liquids in capillary tubes placed perpendicular to the surface. The forces operating within capillarity are cohesion, adhesion, and surface tension. Wikipedia does not have an article with this exact name. ... This article or section does not cite its references or sources. ... A liquid will assume the shape of its container. ... In jewelry, a solid gold piece is the alternative to gold-filled or gold-plated jewelry. ... This article focuses on water as it is experienced in everyday life. ... General Name, Symbol, Number mercury, Hg, 80 Chemical series transition metals Group, Period, Block 12, 6, d Appearance silvery white Atomic mass 200. ... Capillary action or capillarity is the ability of a narrow tube to draw a liquid upwards against the force of gravity. ... In physics, a force is anything that causes a free body with mass to accelerate. ... Dew drops adhering to a spider web Water droplets adhering on a hibiscus petal Adhesion is the molecular attraction exerted between bodies in contact. ... In physics, surface tension is an effect within the surface layer of a liquid that causes the layer to behave as an elastic sheet. ...


Capillary action helps us in our daily lives. For example, it makes water rise through the fibres of a kitchen towel. If capillary action did not exist, we would not be able to blot up spills on a table, or ink from a page.

capillarity - HighBeam Encyclopedia (361 words)
CAPILLARITY [capillarity] or capillary action, phenomenon in which the surface of a liquid is observed to be elevated or depressed where it comes into contact with a solid.
Capillarity can be explained by considering the effects of two opposing forces: adhesion, the attractive (or repulsive) force between the molecules of the liquid and those of the container, and cohesion, the attractive force between the molecules of the liquid (see adhesion and cohesion).
Capillarity is one of the causes of the upward flow of water in the soil and in plants.
