Carbonation in Soda
Ever crack open a cold soda, only for it to go flat on you a few hours later?Those"bubbles" or "effervescence" in carbonated soda are caused by carbon dioxide gas dissolved in the liquid. The carbon dioxide gas bubbles provide the pleasant sparkle in the soda and other carbonated beverages. In this science fair activity,the effect of temperature on the carbonation in sodawill be investigated.
- Bottle of club soda or seltzer water
- 8 oz plastic drinking cups
- Medicine thermometer
- Stop watch or clock
- Open a new bottle of club soda.
- Fill three clear plastic cups about ½ full of the soda.
- Fill another empty cup about a third of the way with ice cold water and measure the temperature.
- Fill a second cup about a third of the way with water at room temperature and measure its temperature.
- In a 3rd cup fill it about a third of the way with hot water from the tap and record its temperature.
- Carefully place one of the soda cups in the cold water, place the 2nd cup in the room temperature water and the 3rd soda cup in the hot water. As some below.
