Differences Between Adhesion and Cohesion
Sr.no Adhesion Cohesion
1. Adhesion happens between two dissimilar molecules or substances. When two similar substances or molecules face force of attraction this force is known as cohesion force.
2. Adhesion is generally the force of attraction present between the water molecules and the walls of xylem vessels. Cohesion force is rampant among water molecules.
3. Capillary action and meniscus (the curved surface which is formed by any liquid in a cylinder) are the effects of adhesion. Surface tension, meniscus and capillary action are the effects of cohesion.
4. Adhesion is caused by electrostatic or mechanical forces that exists among two kinds of different substances. Cohesion is caused by hydrogen bonding and Van der Waals forces.
5. A strong adhesion force causes the liquid to spread all over the surface. A strong force of cohesion forms water droplets on any surface
