Log of carbon dioxide vapor pressure.
What is carbon dioxide a gas at room temperature and pressure. To convert heat values to joules per mole values multiply by 44 095 g mol. Gas properties std enthalpy change. Carbon dioxide chemical formula co 2 is a colorless gas with a density about 60 higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms.
Carbon dioxide phase diagram. At a certain pressure the density of supercritical co2 is 0 469 g cm3. It occurs naturally in earth s atmosphere as a trace gas the current concentration is about 0 04 412 ppm by volume having risen from pre industrial levels of 280 ppm. Carbon dioxide co2 is a gas at room temperature and pressure.
However carbon dioxide can be put under pressure to become a supercritical fluid that is a much safer dry cleaning agent than tetrachloroethylene. Heat content data heat of vaporization and entropy values are relative to the liquid state at 0 c temperature and 3483 kpa pressure.
