8/16 - Cohesion, Adhesion and Surface Tension

Front

What property of water causes droplets to take a spherical shape?

Back

Cohesion

Front

What is the term for the attraction between water molecules and other substances, such as a leaf?

Back

Adhesion

Front

What is the phenomenon that allows insects to walk on water?

Back

Surface tension

Front

How does cohesion contribute to surface tension in water?

Back

Cohesion allows strong hydrogen bonds in water to form below the surface, creating surface tension.

Front

What term describes the ability of water to stick to various materials?

Back

Adhesion

Front

Define cohesion in the context of water molecules.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding.

Front

What is surface tension and how is it related to cohesion?

Back

Surface tension is the elastic tendency of a fluid surface, caused by cohesive forces between liquid molecules.

Front

Explain how adhesion and cohesion work together in the process of capillary action.

Back

Adhesion allows water to stick to the walls of a narrow tube, while cohesion pulls the water molecules together, allowing them to rise.

Front

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

Back

Surface tension allows water striders to skate on the surface without sinking.

Front

How does temperature affect the surface tension of water?

Back

As temperature increases, surface tension decreases due to increased molecular motion.
