1. What is the unit of measurement for density?

Correct answer: A

Rationale: Density is defined as mass per unit volume. The most commonly used unit for density in the metric system is grams per liter (g/L). Kilograms per cubic meter (kg/m³) is also a common unit for density, but grams per liter is more frequently used in everyday measurements. Pounds per square inch (psi) is a unit of pressure, not density. Newtons per meter (N/m) is a unit of force per unit length, not density.

2. A scientific theory is:

Correct answer: B

Rationale: Theories in science are constantly evolving and open to revision as new data emerges, unlike personal beliefs or fixed dogmas.

3. Colligative properties of solutions depend on the...

Correct answer: D

Rationale: The correct answer is D: 'Number of solute particles in solution.' Colligative properties, such as boiling point elevation and freezing point depression, depend on the number of solute particles present in a solution, not on the chemical identity of the solute or the concentration of the solvent. This is because the presence of solute particles disrupts the solvent's normal behavior, affecting these properties. Therefore, the number of solute particles in solution directly influences colligative properties, making it the most accurate choice among the options provided.

4. The phrase "a bold new world" is an example of

Correct answer: B

Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.

5. What is the primary function of the epiglottis in the respiratory system?

Correct answer: C

Rationale: The primary function of the epiglottis in the respiratory system is to prevent food from entering the trachea. When we swallow, the epiglottis covers the opening to the trachea, directing food and liquids to the esophagus instead of the airway. This action helps to protect the respiratory system from foreign objects that could obstruct airflow and cause choking or aspiration pneumonia. Filtration of air and production of mucus are functions associated with other respiratory structures like the nasal passages and bronchial tubes, while oxygen exchange in the alveoli occurs in the lungs, not the epiglottis.

6. What information can be obtained directly from the element's atomic number?

Correct answer: B

Rationale: The atomic number of an element represents the number of protons in the nucleus of an atom. This number determines the element's unique identity and its position on the periodic table. The atomic mass (option A) is not directly determined by the atomic number but is a weighted average of the isotopes of an element. The position on the periodic table (option C) is directly related to the atomic number, as elements are arranged in order of increasing atomic number. The chemical properties of an element (option D) are influenced by the number of protons in the nucleus, which is determined by the atomic number.
