What is capillary action?

What is 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.

Which property is responsible for capillary action?

Because water has both adhesive and cohesive properties, capillary action is present. of capillary action. Water is attracted to some other material and then through cohesion, other water molecules move too as a result of the original adhesion.

What is capillary action due to quizlet?

Capillary action occurs because water is sticky, and, thanks to forces of cohesion and adhesion, are attracted. A process powered by adhesion that causes water molecules to move upward through a narrow glass tube.

What is the cause of the phenomenon of capillary rise and depression?

Explanation: Capillarity is a physical phenomenon in which liquids flow without the help of gravity. Capillary action is due to the phenomenon of surface tension of liquid as well as adhesive forces between liquid molecules and molecules of the narrow tube.

What is capillary action in 12th physics?

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.

Which is responsible for capillary rise?

Capillarity is a physical phenomenon in which liquids flow without the help of gravity. Liquid even rise to a height against gravity, through narrow tubes. Capillary action is due to the phenomenon of surface tension of liquid as well as adhesive forces between liquid molecules and molecules of the narrow tube.

How does intermolecular forces affect capillary action?

Capillary Action. Intermolecular forces also cause a phenomenon called capillary action, which is the tendency of a polar liquid to rise against gravity into a small-diameter tube (a capillary), as shown in Figure 11.4. 3. When a glass capillary is is placed in liquid water, water rises up into the capillary.

How do cohesion and adhesion explain capillary action quizlet?

what enables neighboring water molecules to hydrogen-bond to one another? how do adhesion and cohesion explain capillary action? occurs when adhesion to wall is stronger between liquid. capillary action takes water in circular tube and limited due to gravity.

Which is not an example of capillary action?

The correct answer is the Formation of soap bubbles.

What is the phenomenon responsible for capillary rise?

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.
