Dry ice is essentially solid carbon dioxide (CO2), with a density that doesn't exceed 1.6 grams per cubic centimeter.
How is it produced?
1. The carbon dioxide is compressed into a container and cooled until it changes from gaseous to liquid form.
2. The pressure applied in the first step is reduced, causing some of the liquid to evaporate. As this happens, the remaining material quickly cools and solidifies.
3. The newly formed material, which is the 'dry' ice, is then pressed into molds.
Industrial uses:
1. Refrigerating food products
2. Cooling various types of machinery
3. Creating special effects (like those at weddings, for example)
4. Cleaning surfaces from various substances
5. Producing carbon dioxide for different systems, such as the fuel tank of a B47 aircraft, and more.
