Properties of Water - total

Front

What type of bonds exist between two water molecules?

Back

Hydrogen bonds are the weak attractions between the hydrogen atom of one water molecule and the oxygen atom of another.

Front

What property of water gives certain insects the ability to walk on water?

Back

Surface tension is the property of water that allows it to resist external force, enabling some insects to walk on its surface.

Front

Which property of water allows it to dissolve many substances, making it a universal solvent?

Back

Polarity is the property of water that allows it to interact with and dissolve various substances.

Front

What is the ability of a substance to absorb and retain heat?

Front

True or False: Liquid water is more dense than ice (solid water).

Back

True. Liquid water is denser than ice, which is why ice floats.

Front

What is cohesion in the context of water?

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding.

Front

What is adhesion in the context of water?

Back

Adhesion is the property of water molecules to stick to other substances, which helps in capillary action.

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 is the heat of vaporization?

Back

The heat of vaporization is the amount of energy required to convert water from liquid to gas at its boiling point.

Why is water considered a universal solvent?

Back

Water is considered a universal solvent because it can dissolve more substances than any other liquid due to its polarity.
