Cohesion is the combined effect of the forces of attraction between particles close to each other in the same substance.
Surface Tension is the cohesion at the surface of liquids. Detergents and liquid temperature affect surface tension.
Examples of Cohesion and Surface Tension
- the rounded shape of a water droplet, clasped pointed hands of divers
to reduce surface tension, reduction of surface tension for divers by
fountains spraying into the diving pool
Adhesion is the combined effect of the forces of attraction between the particles in different substances close to each other.
Capillary Action is the effect that
causes liquids to rise or fall in fine tubes. The finer the tube, the
higher the liquid will rise up the tube.
Meniscus - The meniscus is the
curved surface of a liquid such as water in a glass or mercury in a
thermometer. The curve is caused by the adhesive attraction between the
liquid and its container.
Examples of Adhesion and Capillary Action - Meniscus of water in a glass, the movement of water through the tubes in a tree
