English Grammar
1. Identify the conjunction in the following sentence: He went to the store, but they were already closed.
- A. went
- B. to
- C. but
- D. they
Correct answer: C
Rationale: Conjunctions connect words, phrases, or clauses. "But" joins two contrasting ideas in the sentence.
2. Two identical balls, one made of clay and the other made of steel, are dropped from the same height. Which ball reaches the ground first, neglecting air resistance?
- A. The clay ball due to its lower density
- B. The steel ball due to its higher density
- C. Both balls reach the ground simultaneously
- D. It depends on the initial velocities of the balls
Correct answer: C
Rationale: In a vacuum (neglecting air resistance), the acceleration due to gravity is constant for all objects regardless of their mass or composition. This means both balls will experience the same acceleration and reach the ground at the same time.
3. What is the stoichiometric coefficient of nitrogen (N2) in the balanced equation for the Haber process: N2 + 3H2 → 2NH3?
- A. 1
- B. 2
- C. 3
- D. 4
Correct answer: a
Rationale: The coefficient of N2 is 1 in the balanced equation
4. How does an increase in surface area affect the force of friction between two surfaces?
- A. Increases friction
- B. Decreases friction
- C. Has no effect on friction
- D. Causes unpredictable changes in friction
Correct answer: b
Rationale: Increasing surface area reduces the force per unit area, decreasing friction.
5. Which of the following properties is NOT characteristic of a covalent bond?
- A. Sharing of electrons between atoms
- B. High melting and boiling points
- C. Low electrical conductivity in solid state
- D. Directional bonding
Correct answer: B
Rationale: Covalent bonds are formed by the sharing of electrons between atoms. This sharing results in the formation of molecules with directional bonding, where the atoms are held together in a specific orientation. Covalent compounds generally have low melting and boiling points compared to ionic compounds, as the intermolecular forces in covalent compounds are weaker. Additionally, covalent compounds do not conduct electricity in the solid state because the electrons are localized between the atoms and not free to move and carry charge.
6. How does kinetic energy change when the velocity of an object is doubled?
- A. Kinetic energy is halved
- B. Kinetic energy quadruples
- C. Kinetic energy doubles
- D. Kinetic energy remains the same
Correct answer: b
Rationale: Kinetic energy is directly proportional to the square of the velocity of an object.
