Air bubbles are small pockets of air trapped in a liquid or solid. They can form in various substances, such as water, soap, or even ice. When air is introduced into a liquid, it can create bubbles that rise to the surface due to buoyancy. This phenomenon is commonly seen in carbonated drinks, where carbon dioxide gas forms bubbles that create fizz. In nature, air bubbles can also be found in bodies of water, where they may be produced by underwater plants or animals. These bubbles can affect the water's surface tension and play a role in processes like photosynthesis and gas exchange. Understanding air bubbles is important in fields like chemistry and environmental science.
