Explain why the solubility of oxygen in water decreases with increasing temperature, referencing relevant scientific principles.

The solubility of oxygen gas in water decreases as the temperature increases. This is because the dissolution of gases in liquids is an exothermic process, meaning it releases heat. According to Le Chatelier's Principle, increasing the temperature shifts the equilibrium to favor the reverse process (gas escaping from the solution), thus reducing solubility. Additionally, higher temperatures increase the kinetic energy of the dissolved gas molecules, making them more likely to escape from the liquid phase into the atmosphere.
