Adhesion, Cohesion & Surface Tension

Front

What is adhesion?

Back

Water's ability to stick to other substances.

Front

What is cohesion?

Back

Tendency of molecules of the same kind to stick to one another.

Front

What is surface tension?

Back

The elastic-like force existing at the surface of a liquid, caused by the attraction of molecules.

Front

What is a polar molecule?

Back

A molecule in which opposite ends have opposite electric charges.

Front

What is water vapor?

Back

The gaseous form of water.

Front

Give an example of adhesion.

Back

Water droplets on a leaf.

Front

Give an example of cohesion.

Back

Water forming droplets on a surface.

Front

How does surface tension affect small objects?

Back

Small objects, like a paperclip, can float on water due to surface tension.

Front

What role does temperature play in surface tension?

Back

Higher temperatures generally decrease surface tension.

Front

What is the relationship between cohesion and surface tension?

Back

Cohesion contributes to surface tension by causing molecules at the surface to be pulled inward.
