The relationship between volume and pressure of gas is what explains why our lungs expand as they fill with air. This relationship is known as Boyle's law, which states that when the volume of a gas increases, its pressure decreases and vice versa, as long as the temperature and amount of gas remain constant.
As we take a breath in, the volume of our lungs increases, creating a lower pressure inside than that of the outside atmosphere. This creates a pressure gradient that allows air to flow from the high-pressure area outside the body into the low-pressure area inside the lungs. The reverse happens during exhalation, as the volume of the lungs decreases and the pressure increases, forcing air out of the lungs.
Boyle's law, therefore, explains the mechanics of breathing and how the lungs expand as they are filled with air. Without this relationship between volume and pressure, air exchange in the lungs would not be possible, making it difficult for us to breathe.
