Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.
This is an accepted version of this page This is the latest accepted revision, reviewed on 10 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all higher than ever before. [6] Electricity generation, heat and transport are major emitters; overall energy is responsible for around 73% of emissions. [7] Deforestation and other changes in land use also emit carbon dioxide and methane.
A runaway greenhouse effect involving carbon dioxide and water vapor has for many years been hypothesized to have occurred on Venus; [91] this idea is still largely accepted. [92] The planet Venus experienced a runaway greenhouse effect, resulting in an atmosphere which is 96% carbon dioxide , and a surface atmospheric pressure roughly the same ...
Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. [6] Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. [7]
Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. [1] In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common.
The reason that greenhouse gases can absorb infrared radiation is their molecular structure. For example, carbon dioxide has two basic modes of vibration that create a strong dipole moment, which causes its strong absorption of infrared radiation. [12] In contrast, the most abundant gases (N 2, O 2, and Ar) in the atmosphere are not greenhouse ...
