What does Henry's Law state about the relationship between gas solubility and partial pressure?

Henry's Law illustrates a fundamental principle regarding the behavior of gases when in contact with liquids. According to this law, the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. This means that as the partial pressure increases, more gas molecules dissolve in the liquid, enhancing the gas's solubility.

This relationship is crucial in various applications, such as understanding how oxygen dissolves in blood or how carbonation is maintained in beverages. The increased pressure encourages gas molecules to enter the liquid phase, aligning with the behavior described by Henry's Law. Therefore, when considering the dynamics of gas solubility in liquids, this principle underpins much of respiratory physiology and various industrial processes involving gases and liquids.

Other statements present alternative scenarios that do not align with the conditions set forth by Henry's Law; for instance, solubility typically decreases with decreasing temperature rather than being only dependent on it, and increased pressure correlates with greater solubility rather than decreased.
