What phenomenon does Henry's Law explain when a can of soda is opened?

• A. Bubbles rise due to temperature increase
• B. Bubbles are released due to pressure decrease
• C. Bubbles remain in solution until opened
• D. Bubbles are irrelevant to gas pressure

Answer: (B)

Henry's Law states that the amount of gas dissolved in a liquid is proportional to the partial pressure of that gas above the liquid. When a can of soda is opened, the pressure inside the can is suddenly released. This decrease in pressure allows the dissolved carbon dioxide (CO2) gas, which was previously under higher pressure in the sealed can, to escape from the liquid solution. As a result, bubbles form and rise to the surface as the gas escapes into the atmosphere. This phenomenon is a direct application of Henry's Law, demonstrating how changes in pressure affect the solubility of gases in liquids.
