Pressure
Changes in pressure have little affect on the solubility of solids and liquids, but pressure strongly influences the solubility of gases. Gas solubility increases as the partial pressure of the gas above the solution increases. Carbonated beverages are a good example. These drinks contain large amounts of carbon dioxide (CO2) dissolved in water. Dissolved CO2 makes the liquid fizz and your mouth tingle. The drinks are bottled under a high pressure of CO2 gas, which forces large amounts of the gas into solution. When a carbonated-beverage container is opened, the partial pressure of CO2 above the liquid decreases. Immediately, bubbles of CO2 form in the liquid and escape from the open bottle,
