### Kinetic Molecular Theory Quiz

1. **Which statement best explains why gases are easily compressible?**
   - **a.** Particles are in random motion.
   - **b.** Particles undergo inelastic collisions.
   - **c.** Particles undergo intermolecular attractions.
   - **d.** Particles travel faster as the temperature decreases.

2. **The volume of a confined gas can be reduced by the application of pressure at constant temperature. The change in volume may be explained by the fact that gaseous molecules:**
   - **a.** take up space.
   - **b.** have varying masses.
   - **c.** are in constant motion.
   - **d.** are relatively far apart.
   - **e.** collide without loss of energy.

3. **Equal volumes of oxygen, carbon dioxide, and methane under the same conditions of temperature and pressure contain the same number of:**
   - **a.** atoms.
   - **b.** electrons.
   - **c.** molecules.
   - **d.** neutrons.
   - **e.** protons.

### Explanation of Concepts:

- **First Question (Kinetic Molecular Theory of Gases):**
  The question checks the student's understanding of the properties of gases and why they are compressible. The correct answer is not explicitly stated, encouraging students to think critically about the properties listed.

- **Second Question (Behaviour of Gaseous Molecules under Pressure):**
  This question tests knowledge of the behaviour of gas molecules under compression while maintaining constant temperature. The correct answer focuses on the fact that gas molecules are generally far apart, allowing for compression (Answer **d**).

- **Third Question (Avogadro's Law):**
  According to Avogadro's Law, equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules, regardless of their chemical nature and physical properties. Therefore, the correct answer is **c. molecules**.

### Graphs/Diagrams:

No graphs or diagrams are associated with these questions. The content relies on understanding theoretical concepts of gas behavior, kinetic molecular theory, and Avogadro's Law.
