Henry's Law

Henry's Law states that the amount of a gas that can dissolve in a liquid is directly proportional to the pressure of that gas above the liquid. In simpler terms, if you increase the pressure of a gas in contact with a liquid, more of that gas will dissolve into the liquid. This principle explains why carbonated beverages are fizzy; when you open a soda, the pressure decreases, and the dissolved carbon dioxide gas escapes, forming bubbles. Essentially, Henry's Law highlights the relationship between gas pressure and its solubility in liquids.
