The solubility of oxygen in water decreases as temperature increases. Think of it like a fizzy drink – it goes flat faster when it's warm! 💡

• Why? As water heats up, its molecules move faster, making it harder for oxygen molecules to dissolve and stay dissolved. They get bumped out more easily.

#Real-Life Applications

#🐠 Aquatic Life

• Fish in Warm Water: Warm water holds less oxygen, stressing aquatic life. This can lead to fish kills and ecosystem imbalances. 🐟
• Example: A lake that experiences thermal pollution from a nearby power plant may see a decline in its fish population due to reduced oxygen levels.

#💧 Water Treatment

• Oxygen Needs: Water treatment plants rely on dissolved oxygen to remove impurities. Higher temperatures reduce oxygen solubility, making treatment less efficient.
• Example: A water treatment facility may have to use additional aeration methods to compensate for reduced oxygen solubility during hot weather.

#🤿 Scuba Diving

• Oxygen in Tanks: Warmer water means less oxygen in compressed air tanks, increasing the risk of hypoxia for divers. ⚠️
• Example: Divers need to adjust their dive plans and air consumption calculations in warmer waters to account for reduced oxygen content.

#🏭 Industrial Processes

• Microbial Action: Many industries depend on dissolved oxygen for microbial processes. Reduced solubility can disrupt these processes.
• Example: Paper mills and food processing plants may face challenges in maintaining proper oxygen levels for waste breakdown during hot weather.
