Properties of Water

Front

What is capillary action?

Back

Capillary action is the ability of water to move up through narrow spaces, such as in paper or plant roots, against the force of gravity.

Front

What is a unique property of water that allows ice to float?

Back

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

Front

Why is water considered a polar molecule?

Back

Water is polar because it has a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.

Front

What is cohesion in relation to water?

Back

Cohesion is the attraction between water molecules that causes them to stick together, forming drops.

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to spread on surfaces.

Front

What happens to water when it freezes?

Back

When water freezes, it expands, which is why ice is less dense than liquid water.

Front

What is surface tension?

Back

Surface tension is the property of water that allows it to form droplets and resist external force due to cohesive forces between water molecules.

Front

How does water's high specific heat benefit the environment?

Back

Water's high specific heat allows it to absorb and retain heat, helping to regulate temperatures in the environment.

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 and surface tension.

Front

What is the significance of water's ability to dissolve many substances?

Back

Water is known as the 'universal solvent' because it can dissolve a wide range of substances, making it essential for biological processes.
