c) r> 宋体) ) )>Dry ice is a solid state of carbon dioxide. Dry ice has a temperature of minus degrees Celsius, so it is very useful in keeping objects frozen or cryogenic. Dry ice can quickly freeze objects and reduce temperatures and can be deployed with isolation gloves. Nowadays, dry ice has been widely used in many aspects. When dry ice is heated, it directly sublimates from the solid state to the gaseous state, directly converting into the gas and omitting the process of turning into the liquid state. Therefore, its phase change does not produce liquid, so we Call it "dry ice". To turn carbon dioxide into a liquid state, the pressure must be increased to .atmospheric pressure before liquid carbon dioxide appears.
