Why is water called the universal solvent?

• It is polar.

• It exists in the universe.

• It dissolves many substances.

• It has oxygen and hydrogen.

What is the only natural substance on Earth found in the liquid, solid, and gas states?

• water

• hydrogen

• oxygen

Why does ice float on liquid water?

• Ice does not float on liquid water.

• It floats because it has lower density than liquid water.

• It has a higher density than liquid water.

• It has the same density as liquid water.

When water molecules stick to each other because of the polar attraction between hydrogen and oxygen atoms, it is called

• adhesion

• cohesion

• specific heat index

• covalent bonding

When water molecules stick to other materials, it is called

• adhesion

• cohesion

• capillary action

• surface tension
