relationship between intermolecular forces and capillarity

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. The flow against the forces of gravity is called capillary action. For e.g. transportation of water from the roots to leaves. Capillary action is the movement of a. Capillary action occurs because of intermolecular forces. Take a Mercury prefers to form intermolecular bonds between itself rather than glass. What is the relationship between boiling points and intermolecular forces?.

How do intermolecular forces affect capillary action?

Applications Practical use of capillary action is evident in all forms of our daily lives. It makes performing our tasks efficiently and effectively. Some applications of this unique property include: The fundamental properties are used to absorb water by using paper towels. The cohesive and adhesive properties draw the fluid into the paper towel.

The liquid flows into the paper towel at a certain rate. A technique called thin layer chromatography uses capillary action in which a layer of liquid is used to separate mixtures from substances.

Capillary action helps us naturally by pumping out tear fluid in the eye. This process cleanses the eye and clears all of the dust and particles that are around the ducts of the eye.

A possible use for capillary action is as a source of renewable energy. By allowing water to climb through capillaries, evaporate once it reaches the top, the condensate and drop back down to the bottom spinning a turbine on its way to create the energy, capillary action can make electricity!

Although this idea is still in the works, it goes to show the potential that capillary action holds and how important it is. Capillary action is evident in nature all around us. The properties allow the water to be transpired by the xylem in the plant. The water starts in the roots and proceeds upward to the highest branches of the plant.

Capillary action - Wikipedia

You will have been taught to always measure the volume of liquid in a measuring cylinder, burette, pipette, etc, by reading from the bottom of the meniscus when viewed at eye level.

Because the glassware you use has been calibrated to measure volumes of water, taking into account the shape, and hence the volume, of the meniscus. This means that if you measure the volume of water in the apparatus above the bottom of the meniscus, you will be overstating the volume of water. If you measure the volume of water in the apparatus below the bottom of the meniscus, you will be understating the volume of water.

What happens if you use your apparatus to measure the volume of a liquid other than water? The truth is that your measurement will only be approximate, because the shape of the meniscus, and hence its volume, will be different to that of water.

You could re-calibrate the apparatus specifically to measure volumes of a different liquid if you need a more accurate measurement. Can you apply this? Take the test now!
