Dry ice is the solid form of carbon dioxide (CO₂).

– Its sublimation temperature at 1 atm is -78.5 °C.

Dry 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.
