Cohesion, Adhesion, Surface tension

Front

What is surface tension?

Back

The tightness across the surface of water that enables objects, like paper clips, to float.

Front

Define cohesion.

Back

The tendency of molecules of the same kind to stick to one another.

Front

What is adhesion?

Back

The attraction between different kinds of molecules.

Front

Describe the role of cohesion in water.

Back

Water molecules are attracted to other water molecules, which helps in forming droplets.

Front

What is capillary action?

Back

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

Front

How does surface tension affect capillary action?

Back

Surface tension helps to pull water molecules together, allowing them to rise in narrow tubes.

Front

Why is capillary action important for plants?

Back

It helps bring water up into the roots and to the branches and leaves.

Front

What forces are responsible for capillary action?

Back

Adhesion, cohesion, and surface tension.

Front

Give an example of cohesion in everyday life.

Back

Water droplets forming on a leaf.

Front

What is the difference between cohesion and adhesion?

Back

Cohesion is the attraction between similar molecules, while adhesion is the attraction between different molecules.
