What is the effect of temperature on the solubility of gases in water?

• A. Higher temperatures increase gas solubility
• B. Temperature does not affect gas solubility
• C. Higher temperatures decrease the solubility of gases
• D. Lower temperatures have no impact on gaseous solubility

Answer: (C)

The relationship between temperature and the solubility of gases in water is influenced by several physical principles, primarily dictated by Henry's Law. According to this law, the solubility of a gas in a liquid is inversely proportional to the temperature of that liquid. As temperature increases, the kinetic energy of gas molecules also increases. This heightened energy results in greater agitation and movement of the molecules, which makes it more difficult for gas molecules to remain dissolved in the liquid. Consequently, as the water temperature rises, the solubility of gases decreases; gases are more likely to escape from the liquid phase into the atmosphere. This is particularly relevant in natural water bodies and is a significant factor to consider in water treatment processes, aquatic life sustainability, and various industrial applications. Thus, the notion that higher temperatures decrease the solubility of gases in water is grounded in well-documented scientific principles, making it the correct response.
