<P> 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 ; 194.7 K ) and the solid sublimes directly to a gas above − 78.5 ° C. In its solid state , carbon dioxide is commonly called dry ice . </P>
