When water sticks to itself, what is taking place?

Cohesion

Adhesion

Capillary Action

Surface tension

What word describes when water is attracted to other substances?

cohesion

adhesion

capillary action

surface tension

Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called

Covalent bonds

Ionic bonds

Polar bonds

Hydrogen bonds

Water is a universal solvent because it...

It can be found anywhere

It freezes when it gets cold

floats when frozen

Dissolves most substances

Which of the following is LEAST likely to dissolve in water?

nonpolar fats and oils

polar sugar molecules

salt made of a positive sodium ion and a negative chloride ion

all of the substances will dissolve easily in water

Sweating allows for cooling of the body temperature. What is the reason for this phenomenon?

Water is an acid.

Water is a versatile solvent.

Water has a high heat of vaporization.

Water has a high heat capacity.

Small insects can walk across the surface of calm water. Their feet push the surface of the water down slightly, somewhat like a person walking across a trampoline, but they do not break the surface. What is the best explanation for why this happens?

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

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

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

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

What property of water allows it to be such a versatile solvent that it is often called the "universal solvent?"

Purity

Polarity

High heat capacity

Expansion upon freezing

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.

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

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.

The water molecule is neutral.

10.

12.

Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?

Water is an acid.

Water is a versatile solvent.

Water has a high heat capacity.

Water acts as a buffer.

13.

Which statement explains why water molecules stick together?

both sides are negative

one side has a positive charge and the other side has a negative charge

one side has a negative charge adn the other side has a neutral charge

both sides are positive

14.

solute

surface tension

cohesion

adhesion

15.
