Question

Define Capillary Action and give some examples of it.

Answer 1

Hint: In order to answer this question, first we will explain the capillary action and then we will explain the action related to the capillary, and then we will give some examples of capillary and we will discuss more about it.

Complete Step By Step Answer:
Capillary tubes (narrow cylindrical tubes) have extremely small diameters. When these small tubes are dipped in liquid, the liquid level in the capillary rises (or falls) in relation to the surrounding liquid level. This activity is known as capillary action, and these tubes are referred to as capillaries.
A wet fluid exhibits this form of capillary action, which is exacerbated by the combined forces of cohesion and surface tension. Capillary action is caused by intermolecular attraction between water molecules and the adhesive force that exists between the capillary walls and the liquid.
Capillary action can be defined as the phenomena of liquids ascending via a tube or cylinder. Adhesive and cohesive forces are principally responsible for this.
Because of the interaction between the phenomena, the liquid is drawn higher. The higher the liquid rises, the narrower the tube. If one of the two phenomena, surface tension or the ratio of cohesion to adhesion, increases, the rise will increase as well. The ascent of the liquid in the capillary will be lessened if the density of the liquid increases.
The power with which the capillary rises is also determined by the amount of water trapped in it. The substance that surrounds the pores not only fills them but also forms a coating on top of them. The solid materials that are closest to the water molecules have the strongest adhesion. As water is supplied to the pore, the thickness of the film thickens and the magnitude of capillary force decreases.
The uptake of water in paper and plaster (two porous materials), the wicking of paint between the hairs of a paintbrush, and the transport of water through sand are all examples of capillary action.

Note:
The spontaneous flow of a liquid into a narrow tube or porous substance is referred to as capillary action. The force of gravity is not required for this movement to occur. In fact, it frequently works against gravity.
