 * THE STUDY OF THE EFFECT OF DRY ICE ON THE TEMPERATURE OF WATER **
 * Justin T **


 * ABSTRACT: **

The purpose of this study was to find out how much the temperature of water would change over time after Dry Ice was added to it. Dry Ice is a solid form of carbon dioxide gas is extremely cold and can be used for many different purposes. To do the experiment, Dry Ice was put into a beaker with 250 (ml) of water and the temperature of the water was recorded after 1, 2, 3, and 4 (min). It found that the biggest temperature change happened between 1 (min) and 2 (min). This probably happened because as the temperature of the water got closer to the temperature of the Dry Ice, it became harder to drop so it took longer for the temperature to drop further.


 * CONCLUSION: **

In the original experiment, it was found that the longer the Dry Ice was in the water, the colder the temperature of the water would become. These results can be important to the world if someone wanted to use Dry Ice to keep something cold. If they saw the results of this experiment, they would have an idea of how much Dry Ice to use and how long Dry Ice would keep things cold. The hypothesis for this experiment was correct that the longer the Dry Ice was in the water, the colder the water. It was also discovered that the longer the Dry Ice had been in the water for, the less the temperature changed. Experiments that could be conducted in the future are things like seeing if how long it would take a balloon to explode after it is put on top of a Gatorade bottle and the Gatorade bottle is filled with Dry Ice and water.
