It does not burn, and under normal conditions, is stable, inert and nontoxic. Although it is not a poison, it can cause death by suffocation if inhaled in large amounts. Carbon dioxide occurs in nature both free and in combination. Because it is a product of combustion of carbonaceous fuels (e.g., coal, coke, fuel oil, gasoline, and cooking gas), there is usually more of it in city air than in country air. Some sources indicate that the natural balance of carbon dioxide in the atmosphere is growing from its stable level of 0.13% to a predicted 0.14% by the year 2000. It is anticipated that this extra carbon dioxide will fuel the greenhouse effect, warm the atmosphere, and further disrupt the natural carbon dioxide cycle (see global warming).
a colorless, odorless, nonflammable gas produced in respiration, and given off by the tissues to the blood, to be exhaled by the lungs in exchange for oxygen.
Also known as CO2. A colorless, odorless, incombustible gas that has many purposes such as dry ice, the carbonation in carbonated beverages, and in fire extinguishers. CO2 is present in the atmosphere and formed during respiration. CO2 is a compound gas made of oxygen and carbon. CO2 stores it's energy when it is in a liquid state and releases it into a usable force through expansion into a gas. Used in paintguns as a pressurized gas (power source) for shooting paintballs out of the paintgun's barrel. With respect to semi auto paintguns, CO2 is also used for recocking the paintgun.
CO2, a compound consisting of one carbon and two oxygens. It is a reactant in photosynthesis and necessary for plant life. Abundant in the atmosphere due to anthropogenic and natural activities. It is a greenhouse gas. [Journal of Geophysical Research;v96; 7301-7312;1991] [Environmental Science and Technology;v28; 1565-1576;1994
Carbon dioxide is a colorless and odorless gas formed in the tissues during metabolism and carried in the blood to the lungs, where it is exhaled (an increase in the concentration of this gas in the blood stimulates respiration). Carbon dioxide occurs in small amounts in the atmosphere (0.04% volume); it is used by plants in the process of photosynthesis. Its chemical symbol is CO2.
(CO2) A colorless, odorless, non-combustible gas. Humans and all other living organisms give off carbon dioxide in respiration and decomposition. Trees and other plants absorb it and use it during photosynthesis. Also emitted as a by-product of burning fossil fuels.
a colorless, odorless, nonpoisonous gas that is a normal constituent of ambient air. It does not have a direct adverse human health effects, although it is a greenhouse gas that traps the earth's heat, contributing to the potential for global climate change.
Greenhouse gas, non-toxic, colourless and odourless gas that results primarily from the combustion of energy sources containing carbon
A gas which is product of combustion resulting when carbon units with sufficient oxygen to produce complete combustion. Carbon dioxide is a component of many natural gases.
A gas byproduct of metabolism that is removed from the blood by the lungs.
n. CO2 is a colorless gas that is harmful to human beings when breathed in concentrations of 10% or higher, leading to asphyxiation. CO2 is also a normal byproduct of human respiration and yeast fermentation. When CO2 is dissolved into beer, either as part of the fermentation process or by forced pumping, it is called carbonation, and results in the "head" of foam that is characteristic of a well-poured brew.
chemical formula CO2, carbon dioxide is an asphyxiant with a TLV of 5,000ppm. Carbon dioxide is used in cleaning equipment and is a by product of photoresist stripping operations.
One of the two main end products in fermentation of beer by yeast. The source of the effervescence in beer. Also written as CO2. See carbonation above.
A naturally occurring gas, also a by-product of burning fossil fuels and biomass, as well as land-use changes and other industrial processes. It is the principal anthropogenic greenhouse gas that affects the Earth's radiative balance. It is the reference gas against which other greenhouse gases are measured and therefore has a Global Warming Potential of 1. ()
A colorless, odorless, tasteless gas in the air necessary for plant life. Occurs naturally in the atmosphere at .03%.
This gas is both odorless and colorless, and is formed by all organisms during respiration. This gas is used by pond plants, during the process of photosynthesis. This is useful for plants at a level of 15 – 30 ppm; however, it is dangerous to fish above 40ppm.
A colorless, odorless, non-poisonous gas that is a normal part of the ambient air. Carbon dioxide is a product of fossil-fuel combustion. Although CO2 does not directly impair human health, it is a greenhouse gas that traps the earth's heat and contributes to the potential for global warming.
A gas, which when present in the water, provides necessary nutrients for the algae to photosynthesise and reproduce in the presence of sunlight. Also used to lower pH in large pools.
A gas generated by the metabolic process of generating energy to sustain life. Carbon Dioxide "CO2" is normally regulated through the breathing process where CO2 (with its high dissolved PPCO2) is moved out of the bloodstream, and Oxygen (with its high ambient PPO2) is moved into the bloodstream. In normoxic air the percentage of CO2 is negligible, about 0.03%. CO2 appears to be a factor in DCS, narcosis, hyperoxia and Hypoxia.
a heavy colorless gas that does not support combustion, dissolves in water to form carbonic acid, is formed in animal respiration and in the decay or combustion of animal and vegetable matter, and is absorbed from the air by plants in photosynthesis.
CO2 is a colorless, odorless, non-poisonous gas that is a normal part of the ambient air. Of the six greenhouse gases normally targeted, CO2 contributes the most to human-induced global warming. Human activities such as fossil fuel combustion and deforestation have increased atmospheric concentrations of CO2 by approximately 30 percent since the industrial revolution. CO2 is the standard used to determine the "global warming potentials" (GWPs) of other gases. CO2 has been assigned a 100-year GWP of 1 (i.e., the warming effects over a 100-year time frame relative to other greenhouse gases).
Chemical Formula CO - the benchmark against which all other greenhouse gases are measured in terms of their global warming effect.
A heavy colourless gas that is formed especially in animal respiration and in the decay or combustion of animal and vegetable matter. CO2 is absorbed from the air by plants in photosynthesis. It is one of the greenhouse gases.
A gas made up of two atoms of carbon and one atom of oxygen which is produced whenever carbon-based fuels are burned (or oxidized more slowly in plants and animals). Carbon dioxide is the most important "greenhouse gas" which may cause climate change. Human sources of carbon dioxide include burning fossil fuels for electricity, transportation, heating, cooling, and manufacturing. Burning trees in the process of deforestation also produces carbon dioxide. Abbreviated CO2.
Gas containing carbon and oxygen, present in the atmosphere, and given off by volcanoes.
Common gas found in the atmosphere. Has the ability to selectively absorb radiation in the longwave band. This absorption causes the greenhouse effect. The concentration of this gas has been steadily increasing in the atmosphere over the last three centuries due to the burning of fossil fuels, deforestation, and land-use change. Some scientists believe higher concentrations of carbon dioxide and other greenhouse gases will result in an enhancement of the greenhouse effect and global warming. The chemical formula for carbon dioxide is CO2.
a naturally occurring greenhouse gas in the atmosphere, concentrations of which have increased (from 280 parts per million in preindustrial times to over 350 parts per million today) as a result of humans' burning of coal, oil, natural gas and organic matter (e.g., wood and crop wastes).
A colorless, odorless gas produced by respiration and combustion of carbon-containing fuels. Plants use it as a food.
A colorless, odorless gas that occurs naturally in the Earth's atmosphere. Significant quantities are also emitted into the air by fossil fuel combustion.
A harmless, odorless gas composed of carbon and oxygen. It is the byproduct of complete combustion. But it is also a greenhouse gas that contributes to global warming.
A naturally-occurring gas (CO2) present in the atmosphere and formed by the decay of organic matter. Carbon dioxide is naturally present in air to the extent of 0.03 percent by volume and 0.05 percent by weight, in rainwater at 2 to 6 ppm, and in most water supplies from zero to 50 ppm. Carbon dioxide is the gas in carbonated beverages. Dissolved in water, it can form carbonic acid (H2CO3).
