What is the term for the attraction between water and other substances?

Back

Adhesion

Front

What two elements make up a water molecule?

Back

Hydrogen and Oxygen

Front

What is surface tension?

Back

The cohesive force between liquid molecules at the surface that makes it behave like a stretched elastic membrane.

Front

What is capillary action?

Back

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

Front

Why is cohesion important for water?

Back

It allows water to form droplets and contributes to its high surface tension.

Front

How does adhesion benefit plants?

Back

It helps water stick to the surfaces of plant tissues, aiding in water transport.

Front

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

Back

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

Front

What is the significance of capillary action in soil?

Back

It helps water move through soil to reach plant roots.

Front

How does temperature affect surface tension?

Back

As temperature increases, surface tension generally decreases.
