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.
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
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.

That is capillary attraction.
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.
It does not rise or fall. It is an imaginary line.
The rise of water is called capillary action, which occurs when water travels upwards in a narrow space, such as a tube, due to adhesive and cohesive forces. The fall of water due to gravity is called drainage or runoff, where water flows downhill following the path of least resistance.
