What is adhesion in relation to water?

Back

Adhesion is the property of water that describes its ability to be attracted to other substances, allowing it to stick to surfaces.

Front

Which atom in a water molecule has a negative charge?

Back

The oxygen atom in a water molecule has a more negative charge compared to the hydrogen atoms.

Front

Why does water have slight charges in different parts of the molecule?

Back

Water has slight charges because the oxygen end is slightly negative and the hydrogen ends are slightly positive, creating a polar molecule.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that describes its ability to stick to itself, which is why water droplets form.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, often seen in plants as water moves up from roots to leaves.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat means it can absorb a lot of heat before its temperature changes, helping to regulate temperatures in the environment.

Front

What is surface tension?

Back

Surface tension is the elastic tendency of water's surface, allowing it to resist external force, which is why some insects can walk on water.

Front

What is the role of water in the environment?

Back

Water plays a crucial role in the environment by supporting life, regulating climate, and participating in various geological and chemical processes.
