koldioxidmolekylerna

Koldioxidmolekylerna is the Swedish term for carbon dioxide molecules. A carbon dioxide molecule has the chemical formula CO2. This means it consists of one carbon atom covalently bonded to two oxygen atoms. The molecule is linear in shape, with the carbon atom in the center and the oxygen atoms on either side.

Carbon dioxide is a gas at standard temperature and pressure. It is colorless and odorless. While not flammable, it can act as a fire suppressant by displacing oxygen. CO2 plays a crucial role in Earth's climate as a greenhouse gas, trapping heat in the atmosphere. It is also essential for life, as plants use it during photosynthesis to produce energy.

The carbon cycle describes the continuous movement of carbon atoms between the atmosphere, oceans, land, and living organisms. Carbon dioxide is released into the atmosphere through respiration, volcanic activity, and the burning of fossil fuels. It is removed from the atmosphere through photosynthesis and absorption by oceans. Human activities, particularly the combustion of fossil fuels for energy, have significantly increased the concentration of carbon dioxide in the atmosphere, contributing to global warming.
