Properties of Water 6.6 b - Review

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances, such as leaves.

Front

What is cohesion in relation to water?

Back

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

Front

What does it mean for water to be a polar molecule?

Back

Being a polar molecule means that water has a partial positive charge on one side and a partial negative charge on the other, allowing it to form hydrogen bonds.

Front

What is the freezing point of water?

Back

The freezing point of water is 0 degrees Celsius.

Front

Why does ice float on water?

Back

Ice floats because, as water freezes, it expands and its density decreases.

Front

What is the boiling point of water?

Back

The boiling point of water is 100 degrees Celsius.

Front

What is surface tension in water?

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 the significance of water's high specific heat?

Back

Water's high specific heat means it can absorb a lot of heat without a significant change in temperature, which helps regulate climate.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, due to adhesion and cohesion.

Front

What role do hydrogen bonds play in water's properties?

Back

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