Koltvísyru

Koltvísyru is the Icelandic word for carbon dioxide. It is a chemical compound with the formula CO2. This compound is a colorless gas with a faint but distinct odor. It is naturally present in the Earth's atmosphere and is produced by many natural processes, including respiration, combustion, and volcanic activity. Plants absorb carbon dioxide during photosynthesis.

In human activities, the burning of fossil fuels such as coal, oil, and natural gas is a major source of increased atmospheric carbon dioxide concentrations. This has led to concerns about its role in climate change. Carbon dioxide is also used in various industrial applications, including in the production of carbonated beverages and as a refrigerant. It can be dissolved in water to form carbonic acid, which is a weak acid. Understanding the properties and sources of koltvísyru is important for addressing environmental issues and for various technological processes.
