8/16 - Cohesion, Adhesion and Surface Tension

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of a liquid that causes it to behave as if it were covered by an elastic membrane.

Front

In which states of matter is surface tension found?

Back

Surface tension is only found in liquids.

Front

What property of water allows a paperclip to float on its surface?

Back

Surface tension allows a paperclip to float on water when it is gently placed on the surface.

Front

What is the term for the tightness across the surface of water?

Back

Surface tension.

Front

What phenomenon occurs when water molecules stick to a leaf?

Back

Adhesion occurs when water molecules stick to a leaf.

Front

What is adhesion in the context of water?

Back

Adhesion is the property of water that allows it to stick to other materials.

Front

How does cohesion differ from adhesion?

Back

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

Front

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

Back

Surface tension allows small insects, like water striders, to walk on the surface of water without sinking.

Front

What is the relationship between temperature and surface tension?

Back

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

Front

How does the molecular structure of water contribute to its surface tension?

Back

The polar nature of water molecules leads to strong hydrogen bonding, which contributes to high surface tension.
