Liquid rises in a capillary tube due to capillary action, which is the result of adhesive and cohesive forces between the liquid and the tube. Adhesive forces between the liquid and the tube's surface cause the liquid to be attracted to the tube, while cohesive forces within the liquid molecules help pull the liquid up the tube against gravity.

What is the tendency of a liquid to rise in a small diameter tube called?
The 'capillary effect'. See the link.
What are the examples of capillarity?
Examples of capillarity include the ability of water to rise in a narrow glass tube (capillary action), the spread of ink on paper through capillary action, and the movement of water through the roots and stems of plants.
What we called the tendency of liquid molecules to rise spontaneously up tubes with narrow diameters?
That is capillary attraction.
How does a fluid expansion thermometer work?
A fluid expansion thermometer consists of a bulb filled with a liquid, typically mercury or alcohol, connected to a capillary tube. As the temperature increases, the liquid in the bulb expands and rises up the capillary tube. The temperature is read by measuring the height of the liquid in the tube, which corresponds to the temperature scale on the thermometer.
What is the phenomenon of capillarity?
Capillary action, or capillarity, is a phenomenon where liquid spontaneously rises in a narrow space such as a thin tube, or in porous materials. This effect can cause liquids to flow against the force of gravity. It occurs because of inter-molecular attractive forces between the liquid and solid surrounding surfaces; If the diameter of the tube is sufficiently small, then the combination of surface tension and forces of adhesion between the liquid and container act to lift the liquid
Derive an expression for expression for rise of liquid in a capillary tube?
deduce an expression for height of a liquid in capillary tube. also write practical applications of capillary action.
How capillary rise and diameter depends?
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.
What is the tendency of a liquid to rise in a small diameter tube called?
The 'capillary effect'. See the link.
Why do liquid rise of fall in a capillary tube?
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.
Why does a liquid rise in a capillary tube?
This is due to Surface Tension. The molecules/atoms of the liquid are atrracted by the particles of the solid and thus the liquid rises in the capilliary tube.
Why there is capillary action and why the effect is greater for narrower tubes?
Liquid rises in and out of cappilarry to compansate pressure difference. Rise of a liquid in capillary is indirectly proportional to radius of tube so liquid goes higher in a narrow tube.
Does liquid water rinse higher in a narrow tube or a wide tube?
You mean rise not rinse. Higher in a narrow tube due to capillary action.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
The rise of water in a narrow test tube is called?
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.
The fource which causes liquid to rise in a narrow tube is?
The force that causes liquids to rise in a narrow tube is called capillary action. This phenomenon occurs due to the combination of adhesive forces between the liquid and the tube walls and cohesive forces within the liquid itself. Capillary action is more pronounced in narrower tubes due to the increased surface area for interaction between the liquid and the walls.
How determine the surface tension of liquid using capillary rise method?
The surface tension of a liquid can be determined using the capillary rise method by measuring the height to which the liquid rises in a capillary tube. According to the formula ( \gamma = \frac{h \cdot \rho \cdot g \cdot r}{2} ), where ( \gamma ) is the surface tension, ( h ) is the height of the liquid column, ( \rho ) is the density of the liquid, ( g ) is the acceleration due to gravity, and ( r ) is the radius of the capillary tube. By accurately measuring these parameters, the surface tension can be calculated. This method relies on the balance between the adhesive forces between the liquid and the tube and the cohesive forces within the liquid.
Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
