Cohesion, Adhesion, Surface tension

Cohesion

The attraction of water molecules to other substances.

The tightness across the surface of water caused by the attraction of water molecules to each other.

Cohesion allows water molecules to stick together, which is essential for processes like water transport in plants.

Adhesion helps water molecules stick to the walls of plant vessels, aiding in the upward movement of water.

The ability of water to flow in narrow spaces against gravity, due to the combined effects of cohesion and adhesion.

Surface tension allows small objects, like paper clips, to float on water and enables insects to walk on water.

As temperature increases, surface tension decreases because the kinetic energy of water molecules increases.

Cohesion contributes to surface tension by causing water molecules at the surface to be pulled inward, creating a 'skin' effect.

Cohesion helps water molecules stick together while adhesion allows them to stick to plant surfaces, facilitating water transport.
