What occurs when a gas is dissolved in a liquid regarding temperature and pressure based on Henry's Law?

• A. The solubility decreases with temperature increase
• B. The solubility increases with temperature increase
• C. The solubility remains unchanged
• D. The solubility is unaffected by pressure changes

Answer: (A)

According to Henry's 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 pressure increases, more gas can be dissolved in the liquid. However, temperature plays a significant role in gas solubility. When considering temperature, the principles of gas solubility state that as temperature increases, the solubility of gases in liquids generally decreases. This is because higher temperatures provide more energy to the gas molecules, making them more likely to escape from the liquid into the gas phase. Hence, the correct option is that the solubility decreases with an increase in temperature. Understanding these principles is important in various applications, including physiological processes, beverage carbonation, and environmental science, as they help predict how gases behave when mixed with liquids under changing conditions.
