Multiple Choice

What is water?

An atom

A molecule composed of 2 parts Oxygen and one part Hydrogen

A molecular compound composed of 2 parts Hydrogen and one part Oxygen

A pure substance composed of 2 parts Hydrogen and one part Oxygen

Multiple Choice

What characteristic is shown in the image?

Polarity

Hydrogen Bonds

Cohesion

Adhesion

Multiple Choice

Why is water a polar molecule?

the electrons are unevenly distributed

hydrogen has stolen an electron from oxygen

because opposites attract

oxygen has given an electron to hydrogen

Multiple Choice

Which end of the water molecule has a slightly positive charge?

the oxygen end

the hydrogen end

both ends are slightly positive

neither end is positive

Multiple Choice

Because water molecules are polar, they are attracted to each other and stick together. What is this bonding called?

covalent bonds

hydrogen bonds

ionic bonds

isotopic bonds

Multiple Choice

What does it mean to say that water is a "universal solvent"?

many different kinds of substances can be dissolved into water

water freezes very quickly

the solid form of water is less dense than the liquid form

water is very acidic

Multiple Choice

Water has _____ specific heat. Meaning, it takes _____ time to warm up a large amount of water.

high/ long

high/ short

low/long

low/ short

Multiple Choice

Water generally has _______ specific heat than air.

higher

lower

the same

Multiple Choice

Water _________ when it freezes, making it ______ dense.

expands; more

contracts; more

expands; less

contracts; less

Multiple Choice

Why does ice float?

As water freezes, it expands and its density decreases.

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

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

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

Multiple Choice

The picture on the left shows water as a ____________.

liquid

solid

Multiple Choice

The picture on the left shows water with ____________.

a higher density than the picture on the right

a lower density than the picture on the right

the same density as the picture on the right

Multiple Choice

The picture on the right shows water with ____________.

a higher density than the picture on the left

a lower density than the picture on the left

the same density as the picture on the left

Multiple Choice

Why does ice float in liquid water?

The molecules in ice are packed more loosely than in liquid water

Ice has a higher density than liquid water

Ice has a lower specific heat than liquid water

The molecules in ice are packed more tightly than in liquid water

Multiple Choice

The fact that water can stick to other substances is called:

Adhesion

Cohesion

Insulation

Multiple Choice

What is cohesion?

Water's ability to stick to itself

Water's ability to stick to other substances

The strength of the cohesion of all the water molecules combined

Tape, glue and other adhesives

Multiple Choice

Surface tension is caused by ...

strong cohesion between water molecules

strong adhesion between the water molecules

condensation

water cycle

Multiple Choice

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.

Multiple Choice

Filling a cup of water fuller than the top without spilling is an example of water displaying ____________.

cohesion

adhesion

Multiple Choice

When water molecules stick easily to other water molecules, this is called what?

cohesion

adhesion

solution

polar molecule

Multiple Choice

A drop of water sticking to a windshield is an example of water displaying ____________.

cohesion

adhesion

Multiple Choice

A water bug walking across the top of water due to surface tension is an example of water displaying ____________.

cohesion

adhesion

Multiple Choice

The tightness across the surface of water that enables paper clips to float is ____________.

adhesion

capillary action

surface tension

polarity

Multiple Choice

Water creeping up the side of a straw is an example of water displaying ____________.

cohesion

adhesion

Multiple Choice

Why does ice float?

As water freezes, it expands and its density decreases.

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

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

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