Final answer:
When gas at 1 atm is bubbled through a beaker of water that is initially saturated with dissolved air, the gas will dissolve into the water. Eventually, the water will become saturated with the gas, and the excess gas will form bubbles and escape from the solution. This process is similar to what happens when carbonated beverages are opened.
Step-by-step explanation:
When gas at 1 atm is bubbled through a beaker of water that is initially saturated with dissolved air, the gas will dissolve into the water. This is because the solubility of a gas in a liquid increases with increasing pressure. So, as the gas is bubbled through the solution, the increased pressure causes more of the gas to dissolve into the water.
Eventually, the water will become saturated with the gas at the increased pressure, and no more gas will dissolve. At this point, the excess gas will form bubbles and escape from the solution.
For example, when carbonated beverages are opened, the drop in pressure causes the dissolved carbon dioxide gas to come out of solution and form bubbles.
