dRY ICE...?

Question

okay so i have to have a topic by tomorrow.
i've been researching for a topic with dry ice.
can someone give me an advanced topic that has to do with dry ice.

whoever gives me a purpose with the topic gets 10 points.
thanks SO much!

oh & also:
Projects involving experimental work with vertebrate animals, humans,
recombinant DNA, body tissue, pathogenic organisms or controlled substances
are NOT Permitted.

^^taken exacly from the science fair rule book thng.

Answer 1

Well, you can set a burning strip of magnesium ribbon on dry ice and it will continue to burn, forming magnesium carbide in addition to magnesium oxide. You may also get some black smoke from the release of soot: 2Mg + CO₂ → 2MgO + C
.

Answer 2

No, an Ice %. does not incorporate dry ice. Dry ice a frozen carbon dioxide (the belongings you breath out). If an ice %. had dry ice in it, while it heated it might burst. it is by way of fact stable carbon dioxide coverts to gas carbon dioxide while it heats up. The gas kind takes up a lots better quantity then the forged kind.

Answer 3

One of the largest 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; examples of materials being removed: ink, glue, oil, paint, mold and rubber. Further, dry ice blasting can replace: sandblasting, steam blasting, water blasting or other (potentially environmentally damaging) solvent blasting

Answer 4

Discuss the chemical process of sublimation - that's what dry ice does at standard temperature and pressure - it doesn't melt, it sublimates (goes from frozen solid directly to gas).

Answer 5

Uses of solid carbon dioxide:
Hope this helps u to extract out your project :

Liquid and solid carbon dioxide are important refrigerants, especially in the food industry, where they are employed during the transportation and storage of ice cream and other frozen foods. Solid carbon dioxide is called "dry ice" and is used for small shipments where refrigeration equipment is not practical.



Carbon dioxide is used to produce carbonated soft drinks and soda water. Candy called Pop Rocks is pressurized with carbon dioxide gas at about 600 PSI. When you put the candy in your mouth, it melts (just like other hard candy) and releases the gas bubbles with an audible "pop". Traditionally, the carbonation in beer and sparkling wine comes about through natural fermentation, but some manufacturers carbonate these drinks artificially.



The leavening agents used in baking produce carbon dioxide to cause dough to rise. Baker's yeast produces carbon dioxide by fermentation within the dough, while chemical leaveners such as baking powder and baking soda release carbon dioxide when heated or exposed to acids.



Carbon dioxide is often used as an inexpensive, nonflammable pressurized gas. Life jackets often contain canisters of pressured carbon dioxide for quick inflation. Steel capsules are also sold as supplies of compressed gas for airguns, paintball markers, for inflating bicycle tires, and for making seltzer. Rapid vaporization of liquid CO2 is used for blasting in coal mines.



Carbon dioxide extinguishes flames, and some fire extinguishers, especially those designed for electrical fires, contain liquid carbon dioxide under pressure. Carbon dioxide also finds use as an atmosphere for welding, although in the welding arc, it reacts to oxidize most metals. Use in the automotive industry is common despite significant evidence that welds made in carbon dioxide are brittler than those made in more inert atmospheres, and that such weld joints deteriorate over time because of the formation of carbonic acid. It is used as a welding gas primarily because it is much less expensive than more inert gases such as argon or helium.



Liquid carbon dioxide is a good solvent for many organic compounds, and is used to remove caffeine from coffee. First, the green coffee beans are soaked in water. The beans are placed in the top of a column that's seventy feet high. The carbon dioxide fluid at about 93 degrees Cel. enters at the bottom of the column. The caffeine diffuses out of the beans and into the carbon dioxide.



Carbon dioxide has begun to attract attention in the pharmaceutical and other chemical processing industries as a less toxic alternative to more traditional solvents such as organochlorides. It's used by some dry cleaners for this reason. (See green chemistry.)



Plants require carbon dioxide to conduct photosynthesis, and greenhouses may enrich their atmospheres with additional CO2 to boost plant growth. It has been proposed that carbon dioxide from power generation be bubbled into ponds to grow algae that could then be converted into biodiesel fuel. High levels of carbon dioxide in the atmosphere effectively exterminate many pests. Greenhouses will raise the level of CO2 to 10,000 ppm (1%) for several hours to eliminate pests such as whiteflies, spider mites, and others.



In medicine, up to 5% carbon dioxide is added to pure oxygen for stimulation of breathing after apnea and to stabilize the O2/CO2 balance in blood.



A common type of industrial gas laser, the carbon dioxide laser, uses carbon dioxide as a medium.



Carbon dioxide is commonly injected into or adjacent to producing oil wells. It will act as both a pressurizing agent and, when dissolved into the underground crude oil, will significantly reduce its viscosity, enabling the oil to flow more rapidly through the earth to the removal well. In mature oil fields, extensive pipe networks are used to carry the carbon dioxide to the injection points.
