The definition of carbon dioxide is a colorless, odorless gas otherwise known as CO2, that is produced through combustion and respiration.
Facts About Carbon Dioxide
Carbon dioxide is one carbon atom that is joined with two oxygen atoms.
The level of carbon dioxide in the atmosphere has risen drastically in the last 150 years, largely due to burning fossil fuels and deforestation.
Carbon dioxide is found in carbonated drinks (the characteristic that creates the bubbles), in human and animal breath when it is exhaled, is produced from the burning of fossil fuels, is used in fire extinguishers and to make fog using dry ice, and is produced from the decaying of vegetable matter.
Too much carbon dioxide affect respiration and cause headaches, difficulty breathing, dizziness, drowsiness, and death.
An example of carbon dioxide is what people exhale when they breathe.
carbon dioxide definition by Webster's New World
a colorless, odorless, incombustible gas, CO, somewhat heavier than air, that is a product of respiration and combustion: produced commercially and used widely in fire extinguishers, carbonated beverages, etc.: in photosynthesis, carbon dioxide and water are absorbed by plants, which synthesize certain carbohydrates and release oxygen into the air
carbon dioxide definition by American Heritage Dictionary
A colorless, odorless, incombustible gas, CO2, formed during respiration, combustion, and organic decomposition and used in food refrigeration, carbonated beverages, inert atmospheres, fire extinguishers, and aerosols. Also called carbonic acid gas.
A colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. It is breathed out of an animal's lungs during respiration, is produced by the decay of organic matter, and is used by plants in photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks. Chemical formula:CO2.
