8/16 - Cohesion, Adhesion and Surface Tension

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

Front

What property of water allows it to stick well to many materials?

Back

The property of water that allows it to stick well to many materials is called adhesion.

Front

How does surface tension allow a paperclip to float on water?

Back

Surface tension allows a paperclip to float on water by creating a tight surface that can support the weight of the paperclip when it is gently placed on the water.

Front

What is cohesion?

Back

Cohesion is the tendency of molecules of the same kind to stick to one another.

Front

Explain the difference between cohesion and adhesion.

Back

Cohesion refers to the attraction between molecules of the same substance, while adhesion refers to the attraction between molecules of different substances.

Front

What role does surface tension play in the behavior of water?

Back

Surface tension plays a crucial role in the behavior of water by allowing it to form droplets and enabling small objects to float.

Front

How does temperature affect surface tension?

Back

As temperature increases, surface tension generally decreases because the molecules have more energy and move apart more easily.

Front

What is the significance of water's high surface tension in nature?

Back

Water's high surface tension is significant in nature as it allows insects to walk on water and helps in the transport of water in plants.

Front

Describe an example of adhesion in everyday life.

Back

An example of adhesion in everyday life is when water droplets cling to a leaf or a glass surface.
