Kolefnistvíoxíð

Kolefnistvíoxíð, also known by its chemical formula CO2, is a naturally occurring chemical compound. It is a colorless gas with no distinct smell or taste at standard temperature and pressure. CO2 is an essential component of Earth's atmosphere and plays a crucial role in regulating the planet's temperature through the greenhouse effect. Plants utilize CO2 during photosynthesis to produce oxygen and energy. It is also a byproduct of respiration in animals and humans, as well as a product of combustion processes, including the burning of fossil fuels. Concentrations of CO2 in the atmosphere have been increasing significantly since the Industrial Revolution, primarily due to human activities such as the burning of coal, oil, and natural gas, as well as deforestation. This increase is a major contributing factor to global warming and climate change. CO2 has various industrial applications, including in the production of carbonated beverages, as a fire suppressant, and in refrigeration as dry ice.
