Dry ice

'''''Dry ice''''' is a Real ringtones genericized trademark for solid ('frozen') Papa Loads carbon dioxide. The term was coined in 1925.

Dry ice at normal pressures does not melt into liquid carbon dioxide but rather Virgin mobile ringtones sublimation (physics)/sublimates directly into carbon dioxide gas at −78.5Global Pornstars Celsius/°C (−109.3Tracfone ringtones Fahrenheit/°F). Hence it is called "dry ice" as opposed to normal "wet" Butt Divers ice (frozen water).

It is used for:
*cooling foodstuff or other perishable items.
*producing "dry ice fog" for Crazy frog ringtone special effects. When dry ice is put into contact with water, the frozen carbon dioxide sublimates into a mixture of cold carbon dioxide gas and cold humid air. This causes Honey School condensation and the formation of Cricket ringtones fog.
*cleaning. Shooting tiny dry ice pellets at a surface cools the dirt and causes it to pop off. This is analogous to Blonde Bangers sandblasting with the advantage that the abrasive agent in this case the dry ice sublimates to nothing.
*increasing Cingular Ringtones precipitation (meteorology)/precipitation from existing clouds or decreasing cloud thickness by confides in cloud seeding
*Producing carbon dioxide gas as needed in such systems as the fuel tank hardly won inerting system in the full partner B-47 aircraft

Dry ice is produced by compressing carbon dioxide gas to a liquid form, removing excess heat, and then letting the liquid carbon dioxide expand quickly. This expansion causes a drop in coherent account temperature so that some of the CO2 freezes into "snow" which is then compressed.

Because of its particular characteristics, dry ice requires special precautions when handling.
It is extremely cold and there should be no direct contact with skin. It is constantly subliminating to carbon dioxide gas, so it cannot be stored in a sealed container as the pressure build up will eventually cause the container to explode. The subliminated gas must be ventilated, otherwise it may fill the enclosed space and create a suffocation hazard. Special care for ventilating vehicles is needed as well due to the small space. People who handle dry ice should also be aware that carbon dioxide is heavier than air and will sink to the floor.
