8/16 - Cohesion, Adhesion and Surface Tension

Surface tension.

Adhesion.

Cohesion is the attraction between water molecules to other water molecules.

Surface tension.

Water sticking to water.

Cohesion refers to the attraction between similar molecules (e.g., water to water), while adhesion refers to the attraction between different molecules (e.g., water to a leaf).

Surface tension can allow small objects, like a paperclip, to float on the surface of water without sinking.

As temperature increases, surface tension generally decreases due to increased molecular movement.

It allows insects to walk on water and helps in the transport of water in plants.

Water molecules are polar, leading to hydrogen bonding, which creates strong cohesive forces.
