### Boyle's Law and Pressure-Volume Relationship

**Question 11: What does Boyle's law state about pressure and volume at a constant temperature and a constant pressure?**

- Pressure and volume will both increase together or both decrease together.
- Pressure and volume will both decrease as temperature and pressure decrease.
- Pressure and volume will both increase as temperature and pressure increase.
- Pressure increases when volume decreases. **(Correct Answer)**

**Explanation:**
Boyle's law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This means when the volume decreases, pressure increases, and vice versa, provided temperature remains unchanged.

**Question 12: Which of the following is a factor on which expiration depends?**

- Contraction of expiratory muscles

**Explanation:**
Expiration depends on the contraction of expiratory muscles, which helps push air out of the lungs by decreasing the thoracic volume and increasing the pressure in the lungs.
