Properties of Water

Front

What is the high heat capacity of water?

Back

Water can absorb a lot of heat before its temperature changes significantly, which helps regulate temperatures in the environment.

Front

Why do large bodies of water have stable temperatures?

Back

Because of water's high heat capacity, they do not fluctuate quickly in temperature.

Front

What is adhesion in the context of water?

Back

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

Front

What are the two elements that make up water?

Back

Hydrogen and oxygen.

Front

Why does ice float on water?

Back

Ice is less dense than liquid water because it expands when it freezes.

Front

What is cohesion in water?

Back

Cohesion is the attraction between water molecules, which allows them to stick together.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

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.

Front

What is the significance of water being a solvent?

Back

Water can dissolve many substances, making it essential for biological processes.

Front

What happens to water molecules when they freeze?

Back

They form a crystalline structure that is less dense than liquid water.
