Sample Exam Questions
Question 1:
What is the primary force that governs the motion of planets orbiting the sun?
• A) Electromagnetic Force
• B) Gravitational Force
• C) Nuclear Force
• D) Frictional Force
CORRECT ANSWER: B) Gravitational Force
Rationale: Gravitational force is the fundamental force responsible for the attraction
between masses, governing the orbits of planets around the sun, as described by
Newton's Law of Universal Gravitation.
Question 2:
Which gas law states that at constant pressure, the volume of a gas is directly
proportional to its absolute temperature?
• A) Boyle's Law
• B) Charles's Law
• C) Avogadro's Law
• D) Dalton's Law
CORRECT ANSWER: B) Charles's Law
,Rationale: Charles's Law states that the volume of an ideal gas is directly proportional
to its absolute temperature (measured in Kelvin) when the pressure remains constant.
This relationship is foundational in understanding gas behaviors.
Question 3:
In a chemical reaction, what change occurs in the reactants and products?
• A) Reactants gain mass.
• B) Products lose energy.
• C) Reactants are transformed into products.
• D) Energy is absorbed or released.
CORRECT ANSWER: D) Energy is absorbed or released.
Rationale: During a chemical reaction, energy changes occur as bonds are broken and
formed, resulting in either the absorption or release of energy. This is a key principle in
thermodynamics related to chemical processes.
Question 4:
What is the primary component of Earth's atmosphere?
• A) Nitrogen
• B) Oxygen
• C) Carbon Dioxide
• D) Argon
CORRECT ANSWER: A) Nitrogen
Rationale: Nitrogen makes up about 78% of Earth's atmosphere, making it the most
abundant gas. Oxygen is the second most abundant at approximately 21%.
Question 5:
Which of the following best describes a hypothesis?
• A) A fact that has been proven.
• B) A testable prediction.
• C) An unchangeable theory.
• D) A conclusion based on observation.
CORRECT ANSWER: B) A testable prediction.
, Rationale: A hypothesis is a proposed explanation for a phenomenon that can be
tested through experimentation and observation.
Question 6:
What unit is commonly used to measure energy?
• A) Meters
• B) Joules
• C) Liters
• D) Grams
CORRECT ANSWER: B) Joules
Rationale: The joule is the standard unit of energy in the International System of Units
(SI). It measures the work done when a force of one newton moves an object one meter.
Question 7:
What is the pH level of a neutral solution?
• A) 0
• B) 5
• C) 7
• D) 7
CORRECT ANSWER: D) 7
Rationale: A pH of 7 indicates a neutral solution, meaning it is neither acidic nor basic.
Solutions with a pH below 7 are acidic, while those above 7 are basic.
Question 8:
In what state of matter do molecules move most freely?
• A) Solid
• B) Liquid
• C) Gas
• D) Plasma
CORRECT ANSWER: C) Gas
