1 :
the property or state of being capillary
. 2 : 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 attraction of the molecules of the liquid for each other and for those of the solid.
What do you mean by capillary or capillary action?
Capillary action is
the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion and surface tension
. It is the ability of a liquid to flow in narrow spaces without the assistance of, and sometimes in opposition to, external forces like gravity.
What is called capillarity?
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 capillarity Class 11?
Hint: Capillarity is
a phenomenon by which the liquid moves without the help of gravity
. The liquid level rises to some height against the gravitational force, through the narrow tube. This action is due to the phenomenon of surface tension of the liquid.
What is capillary action 12th class?
Capillary action is also sometimes called capillarity, capillary motion, or wicking. Capillary action definition is
summed up as the impromptu flow of a liquid into a narrow tube or porous material
. … This is called capillary action. This movement does not need the force of gravity to take place.
What is capillarity give two example?
The rise and fall of liquid in a capillary tube is called capillarity. APPLICATIONS. 1)
towels soak water on account of capillarity
. 2)Oil rises in the long narrow spaces between the threads of the wick as they act as a capillary.
What is capillary tube in physics?
A capillary tube is
a tube with a very fine bore
. The phenomenon of a rise and fall of a liquid inside a capillary tube when it is dipped in the liquid is called capillary action or capillarity. When a glass capillary is immersed in water, the water rises inside the tube.
What is capillarity in physics class 9?
The rise and fall of liquid in a capillary tube
is called capillarity.
What is capillary action in physics class 11?
Capillarity is a phenomenon,
in which we can observe that the surface of the liquid is elevated or depressed when it comes into contact with a solid
. This action is known as capillary action or wicking. Cohesive and adhesive forces are the reason behind this action.
What is capillarity or capillary action give some application of capillarity?
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.
How do you explain capillary action to a child?
Capillary action is the name of the process when liquids, like water, move up through a solid, like a hollow tube or spongy material. This happens because of the
forces of cohesion, adhesion, and surface tension
. Plants need capillary action to move the water and nutrients they need up into their stalks or trunks.
What is the reason for capillarity?
Capillary action or capillarity is caused
when the adhesive force is stronger than the cohesive force
. Cohesive force is the force between the water molecules. Adhesive force is the force between the water molecules and the walls of the vessels.
What is capillary action 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 capillary action class 10th?
Capillary action is caused by a combination of two different types of intermolecular forces –
cohesive forces and adhesive forces
. The cohesive forces of the liquid and the adhesive forces that arise between the tube and the liquid, together, result in the rise of the liquid through the capillary tube.
What is capillary action in biology quizlet?
Capillary action is
the movement of liquid to the molecules of the solid
; such as in a stem.
What is capillary for kids?
A capillary is a
blood vessel
. … Capillaries are small, and smaller than any other blood vessels. They are about 5-10 μms big, which connect arteries and venules, and enable the moving of water, oxygen, carbon dioxide, as well as many other nutrients and waste chemicals between blood and surrounding tissues.
What is capillary action in plants?
Water moves through the plant by means of capillary action. Capillary action occurs
when the forces binding a liquid together (cohesion and surface tension) and the forces attracting that bound liquid to another surface (adhesion) are greater than the force of gravity
.
What is soil capillarity?
Capillarity. This refers to
how well water rises up in the soil
. Capillarity can be measured by the speed at which water rises in the soil and the extent to which the water rises. Capillarity depends on the size of the spaces between soil particles. The smaller the spaces, the higher the water rises in the soil.
What is the reason for capillary rise and capillary depression?
Capillary depression occurs when
the cohesive force between the molecules of the liquid is higher than the adhesive force between the molecules of the liquid and the molecules of the container
.
