What law explains the solubility of gases in liquids?

• A. Dalton's Law
• B. Archimedes' Principle
• C. Henry's Law
• D. Boyle's Law

Answer: (C)

The solubility of gases in liquids is explained by Henry's Law. This law states that at a constant temperature, the amount of a gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with the liquid. This relationship highlights that if the pressure of the gas above the liquid increases, more gas will dissolve in the liquid.

Henry's Law is especially relevant in various biological and chemical processes, such as respiration, where gases like oxygen and carbon dioxide dissolve in blood, and in industrial applications, including carbonated beverages.

In contrast, the other laws mentioned deal with different principles: Dalton's Law pertains to the behavior of gas mixtures, Archimedes' Principle is related to buoyancy and the upward force experienced by objects submerged in fluids, and Boyle's Law describes the inverse relationship between pressure and volume of a gas at constant temperature.
