1. What is the term for the process of breaking a large molecule into smaller fragments by applying heat?
- A. Polymerization
- B. Hydrogenation
- C. Isomerization
- D. Pyrolysis
Correct answer: D
Rationale: Pyrolysis is the process of breaking down large molecules into smaller fragments by applying heat. The other choices involve different chemical processes.
2. How does the amplitude of a wave relate to its intensity or loudness?
- A. They are inversely proportional.
- B. They are directly proportional.
- C. They have no relationship.
- D. Amplitude affects frequency, not intensity.
Correct answer: B
Rationale: Higher amplitude corresponds to larger displacement from equilibrium and translates to higher intensity or perceived loudness in sound waves.
3. When choosing a color palette for a presentation, it's best to:
- A. Use as many vibrant colors as possible to grab attention.
- B. Stick to a monochrome palette for a minimalist look
- C. Select complementary colors that create harmony and contrast.

- A. Right atrium
- B. Left atrium
- C. Right ventricle
- D. Left ventricle
Correct answer: C
Rationale: The correct answer is C: Right ventricle. The right ventricle receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The right atrium receives deoxygenated blood from the body and passes it to the right ventricle. The left atrium receives oxygenated blood from the lungs and passes it to the left ventricle. The left ventricle then pumps oxygenated blood to the rest of the body. Understanding the flow of blood through the heart chambers is essential for grasping the functions of each chamber in the circulatory system.

6. What is the process of separating a mixture based on the different boiling points of its components called?
- A. Filtration
- B. Chromatography
- C. Distillation
- D. Centrifugation
Correct answer: C
Rationale: This technique separates components based on their boiling points, allowing for the collection of fractions with different boiling ranges.
