Capillarity is
the tendency of a liquid in a capillary tube to rise or fall as a result of surface tension
. Applications of capillarity. 1. The supply of water to the leaves at the top of even a tall tree is through the capillary rise.
What is capillary and its application?
Capillarity : It is
the rise or fall of liquid column in a capillary tube
. Applications of Capillarity : The oil rises through wicks of lamp through capillary action. Any liquid will be absorbed by the sponges through capillary action. Ink will be absorbed by blotting paper.
What are the applications of capillarity?
- The rise of Kerosene in the wick in a Lantern.
- Sucking of ink by the blotting paper.
- The rise of ink in the nib of a fountain pen.
- Sucking of water by the towel.
What is capillarity and examples?
Capillary action is the movement of a liquid through or along another material against an opposing force, such as gravity. … Examples of capillary action in water include
water moving up a straw or glass tube
, moving through a paper or cloth towel, moving through a plant, and tears moving through tear ducts.
What is capillary state any two application of capillary action?
Wicking is the absorption of a liquid by a material in the manner of a candle wick. Paper towels absorb liquid through capillary action, allowing a fluid to be transferred from a surface to the towel. The small pores of a sponge act as small capillaries, causing it to absorb a large amount of fluid.
What is capillarity give two example?
The rise and fall of liquid in a capillary tube is called capillarity. Application is Oil rises in the long narrow spaces between the threads of the wick as they act as a capillary. Capillary rise is due to adhesion. An Example is
water in a glass tube
.
What is the cause of capillarity?
Capillarity is the
result of surface, or interfacial, forces
. The rise of water in a thin tube inserted in water is caused by forces of attraction between the molecules of water and the glass walls and among the molecules of water themselves. … The narrower the bore of the capillary tube, the higher the water rises.
What is capillarity Class 9?
– Capillary action is
the movement of liquid in narrow spaces where there is zero opposition from external forces acting on it
. – For example, when a capillary tube is immersed in water, water level inside the capillary tube rises against the action of gravitational force.
What is capillarity Toppr?
Capillarity is
the tendency of a liquid in a capillary tube to rise or fall as a result of surface tension
.
What is application of viscosity?
1) The
oil used as a lubricant for heavy machinery parts
should have a high viscous coefficient. … Also, it helps to choose oils with low viscosity used in car engines (light machinery). 2) The highly viscous liquid is used to damp the motion of some instruments and is used as brake oil in hydraulic brakes.
What is capillarity formula?
The rise of a column of liquid within a narrow capillary tube is also because of the surface tension. The formula for capillary rise
(h) = 2T/rρg.
What is capillarity simple?
Capillary rise or capillarity is
a phenomenon in which liquid spontaneously rises or falls in a narrow space such as a thin tube or in the voids of a porous material
. … The meniscus is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension.
What is a real life example of capillary action?
Examples of capillary action include
the uptake of water in paper and plaster
(two porous materials), the wicking of paint between the hairs of a paintbrush, and the movement of water through sand.
What is capillary fall in liquids?
Capillary is a phenomenon of
rising or falling of liquid surface in a small tube
compared to the adjacent normal liquid level. The rise of liquid in tube known as capillary rise while depression of fluid level is known as capillary fall.
What is capillarity Shaalaa?
In a
liquid whose angle of contact with solid is less than 90°
, suffers capillary rise. … The rise or fall of a liquid in a narrow tube is called capillarity or capillary action.
What is capillarity in civil engineering?
Capillarity is
the combined effect of cohesive and adhesive forces that causes water and other liquids to rise in thin tubes or other constricted spaces
. … The water continues to climb up the tube until the downward force of gravity on the water equals the upwards force caused by the surface tension.
