In physics, Henry's law is one of the gas laws formulated by William Henry in 1803. It states that:
An equivalent way of stating the law is that the solubility of a gas in a liquid is directly proportional to the pressure of the gas. Henry's law has since been shown to apply for a wide range of dilute solutions, not merely those of gases.
An everyday example of Henry's law is given by carbonated soft drinks. Before the bottle or can is opened, the gas above the drink is almost pure carbon dioxide at a pressure slightly higher than atmospheric pressure. The drink itself contains dissolved carbon dioxide. When the bottle or can is opened, some of this gas escapes, giving the characteristic hiss (or "pop" in the case of a sparkling wine bottle). Because the pressure above the liquid is now lower, some of the dissolved carbon dioxide comes out of solution as bubbles. If a glass of the drink is left in the open, the concentration of carbon dioxide in solution will come into equilibrium with the carbon dioxide in the air, and the drink will go "flat". Note that the pressure acting above the drink in the sealed container must come from the partial pressure of carbon dioxide. If the gas is only air it would not produce the same effect even if the pressure value is the same.
