Cohesion, Adhesion, Surface Tension and Capillarity
Cohesion means inter-molecular attraction between molecules of the same liquid.
Adhesion means attraction between the molecules of a liquid and the molecules of a solid boundary surface in contact with the liquid.
Surface tension is caused by the force of cohesion at the free surface.
Capillarity is defined as the phenomenon of rise or fall of a liquid surface in a small tube relative to the adjacent general level of liquid when the tube is held vertically in the liquid. Capillarity rise or fall is due to the combined effect of adhesion and cohesion
