Final answer:
Boyle's Law simply the volume of a gas is inversely proportional to the pressure at constant temperature. This relationship helps explain phenomena such as breathing mechanics.
Step-by-step explanation:
Boyle's Law is a gas law that states that at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure. This means that as the volume of a gas decreases, its pressure increases, and vice versa, as long as temperature remains constant.
For example, if you have a balloon filled with gas and you squeeze the balloon, the volume of the gas decreases, causing the pressure inside the balloon to increase. On the other hand, if you release the squeeze and let the balloon expand, the volume increases, leading to a decrease in pressure.
This law helps explain various phenomena, such as the mechanics of breathing, where the muscles in our chest cavity decrease the volume of the lungs, increasing the pressure and causing air to be expelled.
