Evaporating+Liquids+To+Inflate+A+Balloon

Lincoln T   Cary Academy ** ABSTRACT  ** The purpose of this experiment was to see if the evaporated gas from carbonated drinks takes a smaller amount of liquid than still water to fill up a balloon on a hot plate. It was hypothesized that carbonated drinks will inflate a balloon quicker than still water. It was also hypothesized that carbonated drinks would fill up the balloon with a less amount of evaporated liquid than still water. The experiment was started by pouring 200 milliliters of liquid into a graduated cylinder and pouring that into an empty Erlenmeyer flask. Then, a balloon was put on the flask and the flask was put on a hotplate. Then, the hotplate was turned up to 5 and the stopwatch was started at the same time. When the balloon inflated, data was recorded. Then, different increments of liquid were tried and recorded. The carbonated drink inflated the balloon quicker than still water and a lesser amount of carbonated liquid inside the flask inflated the balloon quicker than still water. The amount of liquid in the flask increased instead of decreasing and the more liquid in the flask, the greater the increase of liquid after the experiment.
