Front

What word describes when water is attracted to other substances?

Back

Adhesion: The tendency of water molecules to be attracted to different substances.

Front

Why is water considered a universal solvent?

Back

Because it dissolves most substances due to its polar nature.

Front

What is a polar molecule?

Back

A molecule that has an opposite electrical charge on each end, like water.

Front

Where is most of Earth's water found?

Back

In Oceans: Approximately 97% of Earth's water is in the oceans.

Front

What elements make up a water molecule?

Back

2 hydrogen and 1 oxygen: The chemical formula for water is H2O.

Front

What is cohesion in relation to water?

Back

Cohesion: The attraction between water molecules, leading to surface tension.

Front

What is capillary action?

Back

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

Front

What is surface tension?

Back

The elastic-like force at the surface of water that allows it to resist external force.

Front

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

Back

It helps regulate temperature in the environment and organisms.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, allowing ice to float.
