Capillary Action

Movement of water through very small spaces due to molecular forces called capillary forces.

Capillary Action

The means by which liquid moves through the porous spaces in a solid, such as soil, plant roots, and the capillary blood vessels in our bodies due to the forces of adhesion, cohesion, and surface tension. Capillary action is essential in carrying substances and nutrients from one place to another in plants and animals.

Capillary Action

The depression or elevation of the meniscus of a liquid contained in a tube of small diameter due to the combined effects of gravity, surface tension, and the forces of cohesion and adhesion.

When the liquid wets the walls of a container, the meniscus is shaped convex downward; if the liquid does not wet the walls of the container, the meniscus is shaped convex upward.
