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.
Because of different densities (ex. water and oil)
if adhesion>cohesion, concave meniscus from out if ahesion<cohesion, convex if adhesion=cohesion, flat surface
what ia the influence of adhesion and cohesion on liquid
An attraction between substances of the same kind is called cohesion. However, if it occurs in water, then it is known as capillary action.
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.
Cohesion- Is An Attraction Between Molecules Of The Same Substance.Adhesion- Is An Attraction Between Molecules Of Different Substances.
Cohesion and adhesion differ because cohesion is an attraction between molecules of the same substance. Adhesion is an attraction between molecules of different substances.Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other).== == == ==
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.
Adhesion is the attraction between two molecules of different substances.cohesion is the attraction between molecules of the same substances.
Adhesion is when water molecules stick to other molecules
adhesion - when different molecules stick together (water to clothes) cohesion - when molecules of the same type stick together (water to water)
