capillary fall
capillary action
The phenomenon is known as capillary action. It occurs due to intermolecular forces between the liquid molecules and the solid surface of the tube, causing the liquid to either rise or fall, depending on the properties of the liquid and the tube.
The rise and fall is the tides.
Capillary pipes have very tiny holes to enhance the surface tension of the liquid inside, allowing it to rise or fall along the walls of the tube. This facilitates the movement of fluids in the capillary tube without the need for pumps and enables precise measurements in devices like thermometers and pressure gauges.
The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.

Mercury is more dense than water.
It is because of the surface tension between liquid molecules and the inner surface of the tube. The meniscus height is determined by the inner diameter of the tube. The smaller the diameter, the higher the meniscus will climb due to capillary action.
Capillary rise is influenced by the diameter of the capillary tube; specifically, narrower tubes exhibit a greater height of liquid rise due to stronger adhesive forces between the liquid and the tube walls relative to the cohesive forces within the liquid. This phenomenon is described by the capillary action equation, where the height of rise is inversely proportional to the diameter of the tube—smaller diameters lead to higher capillary rise. As the diameter increases, the height of the liquid column decreases, demonstrating the strong relationship between tube size and capillary action.
Capillary reaction refers to the movement of liquids within narrow spaces or porous materials, driven by surface tension, cohesion, and adhesion. This phenomenon is commonly observed in capillary tubes, where liquids can rise or fall against gravity. It plays a crucial role in various natural processes, such as the movement of water and nutrients in plants through their xylem. Additionally, capillary action is significant in various industrial applications, including ink delivery in pens and the absorption of liquids in sponges.

capillary action
The capillary factor, also known as the capillary rise or capillary action, refers to the ability of a liquid to flow in narrow spaces without the assistance of external forces, such as gravity. This phenomenon occurs due to the interplay of cohesive forces within the liquid and adhesive forces between the liquid and the surrounding solid surfaces. In practical terms, it is most commonly observed in thin tubes or porous materials, where liquids can rise or fall against gravity. The capillary factor is crucial in various natural and engineering processes, including the movement of water in soil and plant systems.
