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.
