Adhesion

Front

Why do water droplets form a spherical shape?

Back

Due to cohesion, water molecules are attracted to each other, minimizing surface area.

Front

What is an example of adhesion in nature?

Back

Water droplets on a leaf.

Front

How does cohesion affect the behavior of water in a straw?

Back

Cohesion allows water to be drawn up the straw due to the attraction between water molecules.

Front

What is the difference between cohesion and 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 cohesion?

Back

Surface tension is a result of cohesion, creating a 'skin' on the surface of water.

Front

How does temperature affect the cohesion of water molecules?

Back

As temperature increases, the kinetic energy of water molecules increases, which can reduce cohesion.

Front

What is capillary action and how is it related to adhesion?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, primarily due to adhesion to the walls of the container.

Front

In what way does cohesion contribute to the transport of water in plants?

Back

Cohesion helps to pull water upward through the xylem during transpiration.
