When water molecules stick to other surfaces

Correct Incorrect Correct answer

The property of water that allows it to dissolve polar substances

Correct Incorrect Correct answer

The property of water that allows water to move up a thin tube (or the stem of a plant) by itself

Correct Incorrect Correct answer

3. Question

Match the descriptions of the properties of water next to their correct term.

Sort elements

The ability of water to move upwards against gravity because of cohesion and adhesion.
Water molecules tend to stick together which is why light objects can float or move across the surface of water.
Water can absorb a lot of heat before it gets hot.
Water is able to dissolve more substances than any other liquid because of it's polar nature.

Capillary action

Correct Incorrect Correct answer

Surface tension

Correct Incorrect Correct answer

Specific heat

Correct Incorrect Correct answer

Universal solvent

Correct Incorrect Correct answer

4. Question

Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?

The insects are light enough so they do not break the hydrogen bonds holding the water molecules together

Correct Incorrect Correct answer

The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.

Correct Incorrect Correct answer

The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.

Correct Incorrect Correct answer

The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next

Correct Incorrect Correct answer

5. Question

How can water move from the roots to the leaves of plants?

Water’s cohesion causes it to “pull” towards the leaves

Correct Incorrect Correct answer

Capillary action pulls the water molecules like a chain

Correct Incorrect Correct answer

Water is pulled by gravity

Correct Incorrect Correct answer

Water is pushed by solutes

Correct Incorrect Correct answer

6. Question

Attraction between water molecules is called

Covalent bonds

Correct Incorrect Correct answer

Ionic bonds

Correct Incorrect Correct answer

Polar bonds

Correct Incorrect Correct answer

Hydrogen bonds

Correct Incorrect Correct answer

7. Question

Why does ice float?

As water freezes, it expands and its density decreases.

Correct Incorrect Correct answer

As water freezes, air becomes trapped between the hydrogen bonds of water molecules.

Correct Incorrect Correct answer

As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.

Correct Incorrect Correct answer

As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Correct Incorrect Correct answer

8. Question

Water is polar because…

The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.

Correct Incorrect Correct answer

The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.

Correct Incorrect Correct answer

The molecule has two poles, at which that it is colder than other regions of the molecule.

Correct Incorrect Correct answer

The water molecule is neutral.

Correct Incorrect Correct answer

9. Question

Large bodies of water do not quickly fluctuate in temperature. Why?

Water is a solvent.

Correct Incorrect Correct answer

Water acts as a buffer.

Correct Incorrect Correct answer

Water has a high heat capacity.

Correct Incorrect Correct answer

Water is non-polar.

Correct Incorrect Correct answer

10. Question

What word describes when water is attracted to other substances?

cohesion

Correct Incorrect Correct answer

adhesion

Correct Incorrect Correct answer
