How does temperature generally affect the solubility of oxygen in water?

The relationship between temperature and the solubility of gases in water is well established in environmental science. As the temperature of water increases, the kinetic energy of water molecules also rises. This heightened molecular movement results in a reduced ability of water to keep gases like oxygen dissolved. Consequently, higher water temperatures lead to decreased solubility of oxygen in water.

This principle is crucial for aquatic life, as many organisms rely on dissolved oxygen to survive. Warmer waters can become oxygen-poor, negatively affecting fish and other aquatic organisms that depend on sufficient oxygen levels for respiration.

The other options suggest varying effects of temperature on oxygen solubility, but they do not align with the physical chemistry principles governing gas solubility in liquids. Thus, understanding and recognizing that higher temperatures result in lower solubility of oxygen is essential for comprehending the ecological impacts on water bodies.
