1-3 Classifying matter

Question 1

Physical State

Answer 1

Gas, Liquid, Solid

Question 2

Composition

Answer 2

Element, Compound, Mixture

Question 3

Solids

Answer 3

have definite shape, fixed volume,
Lowest Kinetic Energy

Question 4

Liquids

Answer 4

have no fixed shape and may not fill a
container completely, intermediate kinetic energy

Question 5

Gas

Answer 5

expand to fill their container,
highest kinetic energy.

Question 6

What are mixtures?

Answer 6

A combination of two or more pure
substances

Question 7

Pure Substance-

Answer 7

has well defined
physical and chemical properties.
- can be classified as
elements or compounds.
-Compounds can be further reduced into two or more elements.
- Elements consist of only one type of
atom. They cannot be decomposed or
further simplified by ordinary means.

Question 8

Compounds

Answer 8

Combination of two or more elements in a definite, reproducible way.
 Example: water - H2O

Question 9

Elements

Answer 9

Cannot be converted to a simpler form by a chemical reaction.
 Example: sodium and helium

Question 10

Heterogenous Mixture

Answer 10

does not have
uniform composition. Its components are easily visually distinguishable.
 When separated, the components of both
types of mixtures yields pure substances

Question 11

Homogenous Mixture

Answer 11

consists of two or
more substances in the same phase.
–No optical magnification will reveal
–same properties everywhere
