Question 9 (1 point) Review the question in the image below and choose the most correct answer. The breathing process demonstrates which gas law(s)? a. Gay-Lussac's law b. Boyle's law c. Charles' law d. all of the above a b C d

The correct answer is **b. Boyle's law.**<br /><br />**Explanation:**<br /><br />Boyle's law states that the pressure of a gas is inversely proportional to its volume at a constant temperature. During inhalation, the diaphragm contracts and the lung volume expands. This increase in volume leads to a decrease in pressure within the lungs, causing air to rush in from the higher-pressure atmosphere. During exhalation, the diaphragm relaxes, decreasing lung volume. This decrease in volume increases the pressure within the lungs, forcing air out.<br /><br />While temperature changes can subtly influence breathing, the primary mechanism is the pressure-volume relationship described by Boyle's law. Gay-Lussac's law relates pressure and temperature at a constant volume, and Charles's law relates volume and temperature at constant pressure. Neither of these laws directly explains the mechanics of breathing.<br />
