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.
In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth .
Carbon dioxide liquid/vapor equilibrium thermodynamic data: Temp. °C P vap Vapor pressure kPa H liq Heat content liquid J/g H vap Heat content vapor J/g
Methane produces a larger greenhouse effect per volume as compared to carbon dioxide, but it exists in much lower concentrations and is more short-lived than carbon dioxide. Thus, carbon dioxide contributes more to the global greenhouse effect than methane. [11] Carbon dioxide is removed from the atmosphere primarily through photosynthesis and ...
Global map of greenhouse gas (GHG) emissions, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale. [1] Annual GHG emissions by region, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale [2] Per capita annual GHG emissions, including agriculture and land use change, measured in ...
While federal land ecosystems in most states are sequestering carbon dioxide on average, California’s lost six times more than any other state during the 17-year period from 2005 to 2021 that ...
This is a list of U.S. states and territories by carbon dioxide emissions for energy use, [1] [2] as well as per capita [3] [4] and by area. [5] The state with the highest total carbon dioxide emissions is Texas and the lowest is Vermont. The state with the highest per capita carbon dioxide emissions is Wyoming and the lowest is New York.
Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
