Properties of Water

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

• vegetable oil

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

When water molecules stick together and create a trampoline like surface, it is called

• surface tension

• capillary action

• adhesion

• cohesion

The ability of water to move upward, against gravity, through small openings is an example of

• specific heat index

• universal solvent

• capillary action

• surface tension

Water is able to dissolve almost all substances on Earth which is why it is called the Universal Solvent. One substance that water cannot dissolve is

• kool-aid mix

• sugar

• salt

• vegetable oil

A paperclip floating on water is an example of what property of water?

• capillary action

• surface tension

• universal solvent

• specific heat index

Water traveling up a plant is what property of water?

• surface tension

• specific heat index

• cohesion

• capillary action
