Water is a polar molecule and thus when a glass tube or any other tube with polar molecules is placed in water, the water molecules will attract the sides of the tube and overcome gravity. The property of water to attract the sides of the tube is called adhesion and the reason water isn't only on the sides but in the middle too is because of cohesion. Cohesion is water's ability to attract and hydrogen bond with itself so the water molecules on the sides of the tube attract other water molecules creating a network that reaches all the way across the tube.

Fountain pen works on principle of?
Gravity and capillary action.
What are the applications of capillary action or capillarity?
Capillary action is also essential for the drainage of constantly produced tear fluid from the eye. Paper towels absorb liquid through capillary action. Chemists utilize capillary action in thin layer chromatography, in which a solvent moves vertically up a plate via capillary action. Dissolved solutes travel with the solvent at various speeds depending on their polarity. With some pairs of materials, such as mercury and glass, the interatomic forces within the liquid exceed those between the solid and the liquid, so a convex meniscus forms and capillary action works in reverse.
What works against gravity as water infiltrates the soil and moves underground?
This force is called capillary action.
Is capillary action a product of adhesion?
The adhesive force of wetting liquids specially water is responsible for capillary action, the capillary action is not possible for Mercury.
What is the disadvantage of capillary action?
Capillary action is bad if you want to keep two liquids separate. Capillary action is difficult to control in terms of flow rate.
What has greatest capillary action?
The narrower the bore of the tube ,the greater is the capillary action. For example :A sponge retains water (on being dipped in water)is due to capillary action.
What the hypothesis for the capillary action?
Capillary action will pull water up the stem to the flower and into the petals.
What is capillary action due to?
The adhesive intermolecular forces between the substance rising (the one experiencing capillary action) and the container (typically a capillary).
What would be A good sentence for capillary action?
A paper towel absorbing liquid is an example of capillary action.
What sentence could you use for the word capillary action?
Water is transferred from the roots to the leaves through the stem by capillary action.
Capillary action occurs when water rises from the water table into?
The capillary fringe
Capillary action is a product of?
Adhesion
