Henry's Law relates to which aspect of gas behavior?

Henry's Law specifically addresses how gases behave when they dissolve in liquids. It states that at a constant temperature, the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of that gas above the liquid. This relationship is crucial for understanding various physiological and environmental processes, such as the uptake of oxygen in the blood or the solubility of carbon dioxide in beverages.

For example, in the context of human physiology, Henry's Law helps explain how oxygen diffuses from the alveoli in the lungs into the bloodstream, where its solubility is influenced by the partial pressure of oxygen in the alveolar air. This principle is also significant in fields such as scuba diving, where understanding gas solubility can prevent decompression sickness.
