__ Dry Ice Information

(Chemistry Behind The Experiment)__ The solid form of carbon dioxide is dry ice. Dry ice has no odour and it is colourless. It is also non-flammable, a little acidic and it is extremely cold it is about -78.5 degrees Celsius so at this temperature the dry ice can go from a solid state into the gaseous state so it sublimates or it can undergo deposition from its gaseous state to a solid state.

Some great facts about dry ice are: ~The first person to published their observation of dry ice was French chemist Charles Thilorier in 1835. When he open a pressurized container of liquid carbon dioxide, he noted that there was a formation of dry ice at the bottom of the container. ~Dry Ice can look like snow or water ice ~The density of dry ice usually ranges from 1.2to 1.6kg/dm3 ~44.01g/mole is the molecular weight of dry ice

Dry ice can be used in the commercial, industrial and scientific applications in the real world. In commercial application dry ice is usually used as a cooling agent. Dry ice can be used to preserve food and it can be used to package food that has to remain frozen and cold without mechanical cooling being used. Dry ice in water has an increase in sublimation transition therefore it can be used in theatre, dance/night clubs and haunted house attractions as fog in a fog machine to provide a dramatic feeling. Because insect such as mosquitos are attracted to dry ice, dry ice makes a very good bait to trap these insects. Some industrial applications where dry ice can be used are when there is residue in the industrial equipment they can take dry ice pellets and shoot them out of a nozzle with compressed air, they can be used to loosen asphalt floors tiles, also dry ice can freeze water in valveless pipes to help make it easier to repair. A scientific application of dry ice would be that it is useful for freezing solutions for a cold chemical reaction.

Because of the temperature of dry ice, when dry ice come in contact with skin, it may cause severe skin damage from frostbite. Therefore as a safety precaution (see caution) if you are handling dry ice you should always wear gloves to protect or hands. Another safety precaution would be that you should only expose dry ice in a well ventilated area with open air. The reason behind this precaution is because dry ice sublimate into a large quantity of carbon dioxide gas. The carbon dioxide gas might displace oxygen in the air and it also might demonstrate a great danger of being deprived of oxygen.
