Carbon Dioxide Physical State At Room Temperature

Carbon dioxide is a gas at standard conditions.

Carbon dioxide physical state at room temperature.

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. 55 c 5 4 bar bar upper limit. 30 c 72 14 bar. It can only exist at a pressure above 5 1 atm 5 2 bar.

Liquid carbon dioxide is the liquid state of carbon dioxide which cannot occur under atmospheric pressure. Carbon dioxide has no liquid state at pressures below 5 1 standard atmospheres 520 kpa. At 1 atmosphere near mean sea level pressure the gas deposits directly to a solid at temperatures below 78 5 c 109 3 f. The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure.

75 psi under 31 1 c temperature of critical point and above 56 6 c temperature of triple point. Lower limit for calculation. The following thermodynamic properties will be calculated. Carbon dioxide co2 cid 280 structure chemical names physical and chemical properties classification patents literature biological activities safety.

194 7 k and the solid sublimes directly to a gas above 78 5 c.
