UNIT 1 OF 10 · Q1–Q6

Unit 1: Matter, Measurement & Scientific Method

Question 1

Which statement describes an extensive property of matter?

A) It depends on the type of substance, not the amount.

B) It changes with the amount of sample that is present.

C) It is the same for all samples of a substance.

D) It describes the ability to react with other substances.

✓ B) It changes

with the amount of

sample that is

present.

Extensive properties (mass, volume, energy) depend on the quantity of matter present.

Intensive properties (density, boiling point) do not.

Question 2

Which of the following describes a CHEMICAL change?

A) Ice melting into liquid water

B) Sugar dissolving in coffee

C) Iron rusting to form iron oxide

D) Aluminum being hammered into a thin sheet

✓ C) Iron rusting to

form iron oxide

Rusting involves a chemical reaction producing a new substance (Fe■O■). Melting,

dissolving, and hammering are physical changes.

Question 3

Which statement describes a heterogeneous mixture?

A) It is made of one type of atom chemically combined.

B) It has uniform composition throughout.

C) It is made of two or more pure substances that are not chemically bonded and appears non-uniform.

D) It cannot be separated by physical means.

✓ C) It is made of

two or more pure

substances that

are not chemically

bonded and

appears

non-uniform.

Heterogeneous mixtures (e.g., salad, sand + water) have visibly different components.

Homogeneous mixtures (solutions) look uniform throughout.
