Adhesion, Cohesion & Surface Tension

Front

What is cohesion?

Back

Cohesion is the tendency of water molecules to be attracted to other water molecules.

Front

What is adhesion?

Back

Adhesion is the ability of water to stick to other substances.

Front

What is surface tension?

Back

Surface tension is the property of water that allows it to resist an external force, due to the cohesive nature of its molecules.

Front

Give an example of adhesion.

Back

An example of adhesion is water droplets sticking to a leaf.

Front

Give an example of cohesion.

Back

An example of cohesion is water forming droplets on a smooth surface.

Front

What happens when water molecules are attracted to other substances?

Back

This phenomenon is called adhesion.

Front

What allows a paperclip to float on water?

Back

The surface tension of water allows a paperclip to float.

Front

What is the relationship between cohesion and surface tension?

Back

Cohesion contributes to surface tension, as the attraction between water molecules creates a 'skin' on the surface.

Front

How does water's polarity affect its adhesive properties?

Back

Water's polarity allows it to form hydrogen bonds with other substances, enhancing its adhesive properties.

Front

What is an example of a situation where cohesion is important?

Back

Cohesion is important in the process of water transport in plants.
