Do you enjoy an aerated soft drink? Have you noticed that the content fizzes and gushes out when you open the cap?
If I take a soft drink bottle from the fridge and open it after shaking it vigorously, the liquid spurts out. Why does it come out so forcefully after shaking?
If the liquid rushes out when a softdrink bottle is opened, it is because carbon dioxide is escaping from the water in the drink.
Carbon dioxide is introduced into the water at high pressure and cold temperatures. Besides causing the liquid to bubble when opened, a little of the carbon dioxide reacts with water to form carbonic acid which gives the drink its refreshing tangy taste.
If you shake a bottle vigorously before opening it, some of the gas in the head of the bottle above the liquid will get dissolved in the liquid. This gas is more than the water in the drink can normally dissolve and so when the bottle is opened the sudden release of pressure will cause the gas to rush out. This will bring the liquid out in a gush.
