Refrigerating substance made of solid carbon dioxide which changes directly from a solid to a gas (sublimates).
solidified carbon dioxide; dry ice sublimates at -78.5 C and is used mainly as a refrigerant
a cold, white substance formed when CO2; is compressed and cooled: Dry ice changes into CO2; gas at room temperatures. For small garden rooms this my be an easy way to add CO2.
frozen gas (carbon dioxide) used to chill food
Solidified carbon dioxide that, at −78.5°C and ambient pressure, changes directly to a gas as it absorbs heat. It is used as a coolant to induce the ice phase for supercooled cloud and fog modification procedures.
