Carbon dioxide
Carbon dioxide (CO2) is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. Although carbon dioxide mainly exists in its gaseous form, it also has a solid and a liquid form. It can only be solid when temperatures are below -78 degrees Celsius. Carbon dioxide is water-soluble only when pressure is maintained. CO2 is used by plants for photosynthesis. However, anthropogenic overproduction of CO2 increases the greenhouse effect, as carbon dioxide is the second most abundant greenhouse gas in the atmosphere after water vapor.
