\nThe correct answer is sublimation.
\n<\/section>\n
\nDry ice is solid carbon dioxide. At atmospheric pressure, solid carbon dioxide changes directly into gaseous carbon dioxide without melting into a liquid. This process is called sublimation. The visible ‘mist’ produced when dry ice is used is actually water vapour in the surrounding air condensing or freezing due to the extremely cold carbon dioxide gas. However, the primary phase transition of the dry ice itself is sublimation, which drives the cooling effect leading to the mist formation.
\n<\/section>\n
\nSublimation is an endothermic process, meaning it absorbs heat from the surroundings, which is why dry ice is so effective as a coolant and for creating effects like mist by cooling ambient water vapour.
