6.6B- Properties of Water

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to be attracted to other substances, causing water to 'stick' to surfaces.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows water molecules to be attracted to each other, resulting in surface tension.

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

Why do water droplets form a 'tear drop' shape?

Back

Water droplets form a 'tear drop' shape due to the pull of gravity and the cohesive forces between water molecules.

Front

True or False: All water molecules are affected by the properties of cohesion and adhesion.

Back

True

Front

What is the difference between adhesion and cohesion?

Back

Adhesion is the attraction between water and other substances, while cohesion is the attraction between water molecules themselves.

Front

Give an example of adhesion in everyday life.

Back

An example of adhesion is when water sticks to a glass surface or when it climbs up a paper towel.

Front

Give an example of cohesion in everyday life.

Back

An example of cohesion is when water beads up on a waxed car surface.

Front

What role does surface tension play in nature?

Back

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

Front

How does temperature affect the properties of water?

Back

As temperature increases, water molecules move faster, reducing cohesion and surface tension.
