Capillary action - Wikipedia
Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.
Capillarity | Surface Tension, Interfacial Forces & Adhesion
2024年11月28日 · capillarity, rise or depression of a liquid in a small passage such as a tube of small cross-sectional area, like the spaces between the fibres of a towel or the openings in a porous material. Capillarity is not limited to the vertical direction.
Capillary Action – What It Is and How It Works - Science Notes and ...
2022年2月27日 · Capillary action is fluid flow through a narrow tube or space from surface tension, cohesion, and adhesion. For example, if you place a thin tube into water, the water flows up the the tube. Other names for the phenomenon are capillarity, capillary motion, and wicking. Capillary action does not require the force of gravity.
Capillarity - Meaning, Definition, Formula, and FAQs - Vedantu
Capillarity is the ability of a liquid to move through a second liquid due to attraction, and is one of the fundamental physical properties of all fluids. It can be defined as the rate at which liquids move across a surface (wetted or not) or between two surfaces.
Capillary Action and Water | U.S. Geological Survey - USGS.gov
2018年6月5日 · Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.
Capillary Action: Definition and Examples - Science Facts
2023年7月28日 · Capillary action is a phenomenon in which liquid flows through a narrow tube without the assistance of any force. It refers to the ascension of liquid through a capillary tube due to forces of adhesion and cohesion and, typically, against gravity. Capillary action occurs when the force of adhesion is greater than the force of cohesion.
Capillary Action - Meaning, Definition, Examples, Adhesion, …
Capillary action is the resultant of intermolecular attraction between the molecules of water and the adhesive force in between the walls of the capillary and the liquid. What Is Capillary Action? We can define capillary action as a phenomenon where the ascension of liquids through a tube or cylinder takes place.
What Is Capillary Action? Definition and Examples - ThoughtCo
2020年1月9日 · Capillary action is defined as the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. In fact, it often acts in opposition to gravity. Capillary action is sometimes called capillary motion, capillarity, or …
What Is Capillary Action? - ScienceABC
2023年10月19日 · Capillary action is the movement of water through a porous material, such as soil, against the force of gravity. The water is drawn up the material by the forces of cohesion and adhesion, which are the attractive forces between the molecules of …
Capillarity Definition & Meaning - Merriam-Webster
: the property or state of being capillary. : the action by which the surface of a liquid where it is in contact with a solid (as in a capillary tube) is elevated or depressed depending on the relative …
