First, the adhesion makes the molecules of water stick to the walls of the plants roots and leaves. Then the cohesion joins the molecules of water together to help them move up the walls of the plants roots and leaves.
This depends. If the molecules are of different kinds (ie: Water and Glass), then it is called adhesion. If they are of the same kind, it is called cohesion.The tendency of molecules of the same kind to stick to one another is known as cohesion. This is what keeps the molecules together a good example being in water.
An attraction between substances of the same kind is called cohesion. However, if it occurs in water, then it is known as capillary action.
Because of different densities (ex. water and oil)
I believe it is cohesion or adhesion.
adhesion
No, Cohesion is when like particles are forced together by the molecular forces. Adhesion is when unlike particles are forced together by molecular force
if adhesion>cohesion, concave meniscus from out if ahesion<cohesion, convex if adhesion=cohesion, flat surface
adhesion - when different molecules stick together (water to clothes) cohesion - when molecules of the same type stick together (water to water)
what ia the influence of adhesion and cohesion on liquid
That is capillary action.

Water and benzene will have a work of adhesion rather than a work of cohesion as this is the work associated with the connection between two things as opposed to cohesion which is the force holding one thing together. The expression for the work of adhesion is: gamma of the liquid vapour interface + gamma of solid vapour interface - gamma of solid liquid interface. Where gamma is surface tension.
Adhesion is when the surface of one thing sticks to the surface of another thing. Cohesion is when the parts of one thing stick to each other. Both words have the idea of things sticking together, but adhesion is two different things whereas cohesion is the parts of a single thing.
Examples of Cohesion *Water clinging to your newly waxed car *Water clinging to a pice of waxed paper The examples above are actually examples of ADHESION not COHESION. ADHESION is the force that attracts two DIFFERENT materials together. COHESION is the sticking of two LIKE substances.
Hydrogen bonds are the reason for cohesion and Van Der Waals equation is the cause of adhesion.
adhesion and cohesion
Cohesion the force of attraction by which the molecules of a solid or liquid tend to remain together (clinging power of the same substance)Adhesion: intermolecular attraction between substances that are unlike and in surface contact, causing them to cling together (like glue to paper)
