\nDry ice is the solid form of carbon dioxide (CO\u2082).
\n<\/section>\n
\n– At atmospheric pressure, solid carbon dioxide sublimes directly into a gas without melting into a liquid, hence the name “dry ice”.
\n– Its sublimation temperature at 1 atm is -78.5 \u00b0C.
\n<\/section>\n
\nDry ice is used as a cooling agent in various applications, such as preserving food, creating fog effects, and cooling materials in laboratories. Liquid carbon dioxide exists under high pressure. Liquid nitrogen and liquid ammonia are different substances with different properties and uses.
