When the carbon dioxide gas is pressurized to about 101,325 Pa at room temperature, when a part of the carbon dioxide vapor is cooled to about -78 \u00b0 C, it freezes into a snow-like solid carbon dioxide. Solidified carbon dioxide has a large heat of vaporization, which is 364.5 J\/g at -60 \u00b0 C. When gasified under normal pressure, the ambient temperature can be lowered to about -78 \u00b0 C, and no liquid is produced, so it is called “\u5e72\u51b0<\/strong>“. <\/p>\n\n\n\n
