• C. Weak acids are better at dissolving salts.
• D. Strong acids have a lower pH.

Correct answer: B

Rationale: Strong acids completely dissociate, leading to a h

3. Nuclear forces are much stronger than electromagnetic forces at the nuclear level. What property best describes this characteristic?

• A. Short-range interaction
• B. Long-range interaction
• C. Repulsive force
• D. Dependent on charge only

Correct answer: A

Rationale: Nuclear forces operate within a very small range compared to electromagnetic forces, impacting only nucleons directly touching each other.

4. Which word has the same root as "unscathed"?

5. A new material is claimed to be stronger than steel. You design an experiment to test this claim. What is the MOST important control variable?

• A. The size of the material samples.
• B. The temperature at which the test is conducted.
• C. The force applied to the material.
• D. The color of the material.

Correct answer: A

Rationale: The size of the material samples is the most important control variable because it ensures that the comparison between the new material and steel is fair and accurate. By keeping the size consistent, any differences in strength can be attributed to the material composition rather than variations in sample size. Controlling for size helps eliminate confounding variables and increases the reliability of the experiment results. Temperature, force applied, and color are not as critical for directly testing the strength comparison between the new material and steel.
