 Henry's Law is applicable to the dissolution of gases in liquids. It states that the amount of a gas dissolved in a liquid is proportional to its partial pressure above the liquid, at a given temperature. Carbonation of soft drinks involves the dissolution of carbon dioxide gas in water, while the dissolution of oxygen in water is important for aquatic life. Dissolution of nitrogen in blood and other body fluids is necessary for respiration. Therefore, options a), b), and c) are real-life examples of Henry's Law, while option d) is not.
