http://www.youtube.com/watch?v=cTP4yp8y_NA Os perigos do Dry ice
-Nota: Nunca se deve guardar Dry Ice em garrafas, ou qualquer outro tipo de recipiente dito normal fechado, pois o dry ice tende a libertar gás, pois este não é mais que dióxido de carbono, e o gás cria pressão no recipiente podendo levar ao seu rebentamento, como se pode ver no vídeo ( o vídeo mostra o que um pouco de dry ice pode fazer, by the way não fiquem com ideias.... )




DRY ICE

Solid carbon dioxide, often known by the genericized trademark "dry ice", is a versatile cooling agent. Unlike water ice at atmospheric pressure it sublimes, changing from a solid directly to a gas. Its sublimation point is -78.5°C (-109.3ºF). A combination of its low temperature, solid phase and direct sublimation to gas makes it a simple and effective coolant. Dry ice is also inexpensive; it costs about US$2 per Kg (US$1 per lb). History Dry ice was first observed in 1825 by the French chemist Charles Thilorier. Upon opening the lid of a large cylinder of liquid carbon dioxide he noted much of the carbon dioxide rapidly evaporates leaving solid dry ice in container. Throughout the next 60 years, dry ice was observed and tested by many scientists. Production Dry ice is readily manufactured; 1. Carbon dioxide is obtained in any of the ways listed above. 2. It is pressurized and refrigerated, until it changes into its liquid form. 3. The pressure is reduced. When this occurs some liquid carbon dioxide vaporises, and this causes a rapid lowering of temperature of the remaining liquid carbon dioxide. The extreme cold makes the liquid solidify into a snow-like consistency. 4. The snow-like solid carbon dioxide is compressed into either small pellets or larger blocks of dry ice. Dry ice is typically produced in two standard sizes; solid blocks and cylindrical pellets. A standard block is most common and will normally weigh about 30 kg (60 lb). These are largely used in the shipping industry because they sublime slowly due to a relatively small surface area. The pellets are around 1 cm (½ inch) in diameter and can be bagged easily. This form of dry ice is more suited to small scale use, for example at grocery stores and laboratories. Safety Dry ice can be a dangerous substance. It must be handled using protective insulated gloves. Direct contact with the skin can freeze it in seconds, causing a burn-like injury. Dry ice must not be stored in a sealed container, since its sublimation produces massive volumes of gaseous carbon dioxide. A sealed container can fail explosively from the pressure, sufficient to cause shrapnel injuries and hearing loss. Furthermore, dry ice should never be stored in a standard freezer or refrigerator. The dry ice is so cold that it can freeze and disable the thermostat of the unit.[citation needed] It can also cause problems through thermal contraction. Dry ice should never be left on brittle surfaces or in glass containers. The contraction caused by cooling can result in cracking. Uses Aside from obvious uses in cooling and shipping, dry ice has many other applications: * In medicine, dry ice can freeze warts and other similar skin conditions, easing their removal. * Dry ice blast cleaning, see below. * Removal of floor tiles - the low temperature makes the tiles shrink and crack. This will loosen them so that they can be removed. * Carbonation of water (and other liquids). This is widely used in the carbonated drinks industry. * Dry ice can repel mosquitoes and other insects due to its low temperature. * Rapid sublimation of dry ice caused by putting it in water produces a dense fog of water vapour. This is a popular dramatic effect, common as a stage effect or in recreation at Halloween. The fog produced, being largely dense carbon dioxide, sinks to the floor. Dry ice blast cleaning One of the most important alternative uses of dry ice around the world is dry ice blast cleaning. Dry ice pellets are shot out of a jet nozzle with compressed air. This can remove residues from industrial equipment, for example ink, glue, oil, paint, mould and rubber, replacing sandblasting, steam blasting, water blasting or other (potentially environmentally damaging) solvent blasting. Dry ice blasting involves three factors: 1. kinetic energy 2. thermal shock 3. thermal kinetic energy. The kinetic energy of the dry ice pellets is transferred when it hits the surface, directly dislodging residues, as in other blasting methods. The thermal shock effect occurs when the cold dry ice hits a much warmer surface and rapid sublimation occurs. The thermal kinetic effect is the result of the rapid sublimation of the dry ice hitting the surface. These factors combine cause small "micro-explosions" of gaseous carbon dioxide where each pellet of dry ice impacts, dislodging the residue. Quoted from Wikipedia.
