Exam Questions
Question 1
What is the primary unit of force in the International System of Units (SI)?
• A) Joule
• B) Newton
• C) Pascal
• D) Watt
CORRECT ANSWER: B) Newton
Rationale: The Newton (N) is the SI unit of force, defined as the amount of force needed
to accelerate a one-kilogram mass at a rate of one meter per second squared.
Question 2
Which of the following is a characteristic of a gas?
• A) Fixed shape
• B) Fixed volume
, • C) No fixed shape or volume
• D) Easily compressible only under certain conditions
CORRECT ANSWER: C) No fixed shape or volume
Rationale: Gases do not have a fixed shape or volume and will expand to fill any
container they occupy, which is a defining characteristic of gases compared to solids
and liquids.
Question 3
In a chemical reaction, what does the law of conservation of mass state?
• A) Mass can be created or destroyed
• B) Mass is always conserved
• C) Mass is lost in exothermic reactions
• D) Products have less mass than reactants
CORRECT ANSWER: B) Mass is always conserved
Rationale: The law of conservation of mass states that in a closed system, the mass of
reactants equals the mass of products. This principle underpins stoichiometry and
chemical reactions.
Question 4
Which of the following best describes the process of photosynthesis?
• A) Conversion of light energy into chemical energy
• B) Breakdown of glucose in the presence of oxygen
• C) Absorption of nutrients from soil
• D) Release of carbon dioxide by plants
CORRECT ANSWER: A) Conversion of light energy into chemical energy
Rationale: Photosynthesis is the process by which green plants convert light energy
into chemical energy stored in glucose. It involves taking carbon dioxide and water and
converting them using sunlight.
Question 5
Which type of wave requires a medium to travel through?
• A) Electromagnetic
, • B) Longitudinal
• C) Transverse
• D) Both B and C
CORRECT ANSWER: D) Both B and C
Rationale: Both longitudinal and transverse waves require a medium (e.g., solid, liquid,
or gas) to propagate. Electromagnetic waves, on the other hand, do not require a
medium.
Question 6
The pH scale describes the acidity or basicity of a solution. What is the pH of pure
water?
• A) 0
• B) 7
• C) 14
• D) 4
CORRECT ANSWER: B) 7
Rationale: Pure water has a pH of 7, which is considered neutral. Values below 7
indicate acidity, while values above 7 indicate basicity.
Question 7
What is the main gas responsible for the greenhouse effect?
• A) Nitrogen
• B) Oxygen
• C) Carbon Dioxide
• D) Argon
CORRECT ANSWER: C) Carbon Dioxide
Rationale: Carbon dioxide (CO2) is a primary greenhouse gas that traps heat in the
atmosphere, contributing to global warming and climate change.
