Properties of Water Review

Front

What are the attractions between water molecules called?

Back

Hydrogen bonds.

Front

What property allows water striders to walk on water?

Back

They are light enough so they don't break the hydrogen bonds holding the water molecules together.

Front

What is the chemical formula for water?

Back

H₂O.

Front

What is cohesion in the context of water?

Back

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

Front

What is adhesion in the context of water?

Back

Adhesion is the property that allows water molecules to stick to other surfaces.

Front

Why do water droplets form beads on a leaf?

Back

Due to adhesion, water molecules stick to the surface of the leaf.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds give water its unique properties, such as high surface tension and specific heat.

Front

How does temperature affect the density of water?

Back

Water is most dense at 4°C; as it freezes, it becomes less dense.

Front

What is surface tension?

Back

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

Front

What role does water play in temperature regulation for living organisms?

Back

Water has a high specific heat, which helps stabilize temperatures in organisms and environments.
