Answers
Hey there!
Dry ice or dry ice is called carbon dioxide (CO2) in the solid state. It receives this name because, despite resembling normal ice or snow due to its appearance and temperature, when sublimated it leaves no residue of moisture because its base is not water and its natural state is gaseous even at low ambient temperatures. It has a sublimation temperature of -78.5 ° C (at an atmosphere of pressure).
Since it is carbon dioxide, it can also be used to fix metal, to remove floor tiles and to remove warts. It can also be found in tools such as fire extinguishers. One of the main uses of dry ice is to preserve perishable foods. It is also used by ice cream parlours to keep the ice cream they sell cold. In the world of spectacle it is also sometimes used to release at ground level a very visible white vapor, similar to cold fog.
When the pressure under which it is stored is decreased to 1 atmosphere then it changes into its original form (Carbon Dioxide).
