SOL 6.6 Water Properties

Front

What is surface tension?

Back

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

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules to each other.

Front

What is the boiling point of water in degrees Celsius?

Back

The boiling point of water is 100 degrees Celsius.

Front

Why can water striders walk on water?

Back

Water striders can walk on water because they are light enough not to break the hydrogen bonds between water molecules.

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve many substances due to its polarity.

Front

What happens to water molecules when they freeze?

Back

When water freezes, the molecules arrange themselves in a crystalline structure, making ice less dense than liquid water.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds are responsible for many of water's unique properties, including its high surface tension and specific heat.

Front

How does temperature affect the density of water?

Back

As water is heated, it becomes less dense; conversely, as it cools, it becomes denser until it reaches 4 degrees Celsius.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion.
