The influence of temperature on the solubility of gases in liquids is rooted in the principles of gas behavior and thermodynamics. As the temperature of a liquid increases, the kinetic energy of the molecules within that liquid also increases. This heightened kinetic energy results in a higher tendency for gas molecules to escape from the liquid into the surrounding environment.

Essentially, warmer temperatures provide gas molecules with more energy to overcome the intermolecular forces that keep them dissolved. Therefore, as temperature rises, the solubility of gases in liquids decreases, leading to a scenario where fewer gas molecules can remain dissolved in the liquid. This principle is commonly observed with carbonated beverages; when a soda is warmed, it becomes less fizzy as the dissolved carbon dioxide gas escapes more readily.

The other choices do not accurately reflect this behavior. Higher temperatures increasing gas solubility contradicts the established understanding of gas-liquid interactions. The notion that temperature has no effect on gas solubility overlooks the significant energetic changes occurring at different temperatures. Similarly, the idea that gas solubility varies directly with temperature changes misrepresents the inverse relationship between temperature and the solubility of gases in liquid mediums.
