,Chapter 1: Chemistry in Our Lives
Question 1
Chemistry is best defined as:
A. The study of planets and stars
B. The study of matter and the changes it undergoes
C. The study of living organisms only
D. The study of electricity
Correct Answer: B
Rationale:
Chemistry focuses on matter, its composition, properties, and transformations.
Question 2
Which of the following is matter?
A. Air
B. Water
C. Table
D. All of the above
Correct Answer: D
Rationale:
Matter is anything that has mass and occupies space, including solids, liquids, and gases.
Question 3
Which is a physical property of matter?
A. Color
B. Flammability
C. Reactivity with acid
D. Oxidation
Correct Answer: A
Rationale:
Physical properties can be observed without changing the substance’s composition. Color, density,
and melting point are examples.
, Question 4
Which is a chemical property?
A. Flammability
B. Density
C. Color
D. Melting point
Correct Answer: A
Rationale:
Chemical properties describe how a substance reacts to form new substances.
Question 5
An example of a chemical change is:
A. Rusting of iron
B. Melting ice
C. Dissolving sugar in water
D. Boiling water
Correct Answer: A
Rationale:
Rusting produces a new substance (iron oxide), making it a chemical change.
Question 6
Which is a physical change?
A. Breaking a glass
B. Burning paper
C. Baking a cake
D. Rusting nail
Correct Answer: A
Rationale:
Physical changes alter shape or phase without forming new substances.
Question 7
Which is an example of matter that is a gas at room temperature?
A. Oxygen
B. Iron
C. Water (ice)
D. Sodium
