1. How does the potential energy of an object change when it is compressed?

• A. Potential energy decreases
• B. Potential energy increases
• C. Potential energy remains constant
• D. Potential energy becomes zero

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

2. Which of the following is NOT a common site for lymph nodes?

• A. Groin
• B. Armpit
• C. Neck
• D. Liver

Correct answer: D

Rationale: The correct answer is D: 'Liver.' Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They are commonly found in areas such as the groin, armpit, and neck, where they help filter and trap harmful substances. The liver, while an important organ in the body, does not typically contain lymph nodes. Therefore, it is not a common site for lymph nodes. Understanding the locations of lymph nodes in the body is important for identifying potential sources of infection or cancer when assessing patients.

3. Which of the following substances is typically a good conductor of electricity when dissolved in water?

• A. Sugar
• B. Sodium chloride
• C. Olive oil
• D. Oxygen gas

Correct answer: b

Rationale: Ionic compounds like sodium chloride dissociate into ions in water, making the solution conductive. The other choices do not typically conduct electricity in water.

4. The energy required to break a chemical bond is called:

• A. Kinetic energy
• B. Potential energy
• C. Activation energy
• D. Bond energy

Correct answer: C

Rationale: Rationale: Activation energy is the energy required to break a chemical bond and initiate a chemical reaction. Kinetic energy (option A) is the energy of motion, potential energy (option B) is stored energy, and bond energy (option D) is the energy required to break a particular chemical bond in a molecule. Among the options provided, activation energy best describes the energy required to break a chemical bond.

5. What is the meaning of the idiom "to bite off more than one can chew"?

• A. To be overly confident
• B. To take on more than one can handle
• C. To be easily discouraged
• D. To be meticulous in planning

Correct answer: B

Rationale: The idiom warns against undertaking a task exceeding one's capabilities.

6. The process of a liquid changing into a gas is called:

• A. Evaporation
• B. Boiling
• C. Condensation
• D. Sublimation

Correct answer: A

Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.
