Facts about Carbon Dioxide

Facts about Carbon DioxideIt is part of the atmosphere, making up about 1% of the volume of dry air. Because it is a product of combustion of carbonaceous fuels (e.g., coke, coal, gasoline, fuel oil and cooking gas), there is usually more of it in city air than in country air.

Chemical compound, CO2, an odorless, colorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of pressure and temperature. It does not burn and under normal conditions it is inert, stable and nontoxic.

Carbon dioxide has different commercial uses. Its greatest use like a chemical is in the development of carbonated beverages; it gives the sparkle in carbonated beverages including soda water. Created by the action of yeast or baking powder, carbon dioxide causes the rising of bread dough.

In different parts of the world notably in Italy, Java and Yellowstone National Park in the United States carbon dioxide is created underground and issues from fissures in the earth.

Carbon Dioxide for Kids

Carbon is a component that is located around the globe and in every living thing. Oxygen is other element that is in the air we inhale. When oxygen and carbon bond with each other, they form a colorless, odorless gas known as carbon dioxide, which is a heat trapping greenhouse gas.

Anytime we burn fossil fuels including oil, coal and natural gas, whether it is to drive our cars, use electrical power or make products, we are generating carbon dioxide.

The atmosphere is not the sole part of the world that has carbon. The seas store huge amounts of carbon and so do plants, soil and deposits of oil, coal and natural gas deep underground.

Carbon naturally moves through one part of the world to another via the carbon cycle. However right now, by burning fossil fuels, human are adding carbon to the atmosphere (in the type of carbon dioxide) quicker than natural processes can eliminate it.

Uses of Carbon Dioxide

Carbon dioxide is used inside the food industry to make carbonated beverages including mineral waters and sodas. It is also used to propel beer on tap and provides this beverage its popular foam.

Carbon dioxide is also used as an inerting atmosphere (for welding or for handling flammable materials, for instance). It produces a protective atmosphere that allows to control the growth of the micro-organisms (bacteria, insect larvae, fungi, etc.) found in food products such as bread and grains, by depriving them of Oxygen.

In addition, Carbon dioxide is used in a few fire extinguishers. It is packaged in the gaseous state however becomes dry ice snow when released. It is able to cool fire and also deprives fire of the Oxygen it needs to burn by displacing air.
