1st Period Properties of Water

Front

What is the charge of the hydrogen end of a water molecule?

Back

Slightly positive charge.

Front

What is cohesion in relation to water?

Back

Cohesion is the property that allows water molecules to stick to each other.

Front

What is surface tension?

Back

Surface tension is the property of water that allows it to resist external force, due to the cohesive nature of its molecules.

Front

What is adhesion in relation to water?

Back

Adhesion is the property that allows water molecules to stick to other substances.

Front

Why is water considered a universal solvent?

Back

Water is a universal solvent because it can dissolve most substances.

Front

What happens to water when it freezes?

Back

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

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces.

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 climate.

Front

What is the molecular structure of water?

Back

Water is made up of two hydrogen atoms and one oxygen atom (H2O).

Front

How does water's polarity affect its properties?

Back

Water's polarity allows it to form hydrogen bonds, leading to unique properties like cohesion and adhesion.
