A.SolidB.WaterC.LiquidD.Gas

B. Water

True or false. A compound can have very different properties than the

elements that make it up.

TRUE.

Proportions in ___________ vary; whereas proportions in __________

remain the same. A.Mixtures; CompoundsB.Compounds; Mixtures

C.Atoms; MoleculesD.Molecules; Atoms

A. Mixtures; Compounds

True or False. Most substances are considered to be pure.

False; most substances are considered to be mixed. Example:

the air you breathe.

There is more space between the particles of a _________ than there is between the particles

of a ________.

A.Liquid; GasB.Gas; LiquidC.Solid; Gas

D.Solid; Liquid

B. Gas; Liquid

Which state of matter is this photo showing?

Gas

True or False. When a molecule changes from one state to

another, the molecules in the substance do not change.

.

TRUE. What does

change???

Which of the following is an example of a physical molecule that you see?

A.Water moleculesB.Molecules in your desk

C.Air molecules (bouncing dust particles)D.Picture frame molecules

Both water molecules and air molecules are acceptable

A _________ is a substance that contains only one type of atom.

Element

What is the ONLY way to separate a compound?

By breaking the bonds between atoms

How is a substance considered to be pure?

If it has only ONE type of component (molecule,

atom—ex: element)

What is a combination of different substances that remain the same individual substances and can be

separated by physical means? Please provide an example as well.

Mixture. Answers may vary—salads, trail mix,

smoothies...etc.

How is a compound different than a mixture?

A. No difference, they are the sameB. Compounds can be separated by physical means, whereas mixtures cannotC. Mixtures are separated by breaking bonds, whereas compounds are not. D. Mixtures are separated by physical means and compounds are separated by breaking bonds between atoms

D. Mixtures are separated by physical means and compounds are separated by breaking bonds between atoms.

True or False. Heterogeneous- the same throughout; homogeneous- varies

throughout .

False. Heterogeneous- varies throughout. Homogeneous- the same

throughout.

Which is NOT an example of a mixed substance?

A. paperB. airC. elementD. wood

Element—pure substance!

Which state of matter does this picture depict?

Solid

This state of matter has particles that can move freely and has NO fixed volume/fixed

shape. Gas

Whether a substance is a solid, liquid, or gas depends on how close its atoms

are to one another and...

How free the atoms are to move

True or False. Gas molecules move faster at higher

temperatures than they do at lower temperatures.

TRUE.

Gas molecules are always in motion; they bounce off one another and the

insides of the container.

How do gas molecules behave in a closed container?
