Carbon Dioxide Physical State At Room Temperature

The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure.
Carbon dioxide physical state at room temperature. The following thermodynamic properties will be calculated. The answer to your question is in the molecular structure of co2 there are 4 electrons in outer orbit of carbon and six in that of oxygen. It can only exist at a pressure above 5 1 atm 5 2 bar. Carbon dioxide has no liquid state at pressures below 5 1 standard atmospheres 520 kpa.
Carbon dioxide co2 cid 280 structure chemical names physical and chemical properties classification patents literature biological activities safety. 30 c 72 14 bar. However at low temperature and or high pressures the gas becomes a liquid or a solid. 75 psi under 31 1 c temperature of critical point and above 56 6 c temperature of triple point.
At 1 atmosphere near mean sea level pressure the gas deposits directly to a solid at temperatures below 78 5 c 109 3 f. 55 c 5 4 bar bar upper limit. Carbon dioxide is a gas at standard conditions. Liquid carbon dioxide is the liquid state of carbon dioxide which cannot occur under atmospheric pressure.
