Sure, there's small amount of volatiles but if you add pure oxygen to a "separated" flame anything oxidizable would be gone in an instant. And if by frozen oxygen you mean oxygen that's been frozen solid there's no way a normal burning reaction could take place at those temperatures. I'm not exactly sure what sort of exact scenario you have in mind.
In a fire there is a chemical reaction and exothermic reaction - that is it produces heat. However, if you can take the heat away faster than the chemical reaction can generate it, then the fire will go out. You need to be a member in order to leave a comment.

Posted June 12, Link to comment Share on other sites More sharing options Pantaz Posted June 12, By adjusting the gas flow, its circulation becomes fast enough to ensure that the ions do not accumulate thermal energy, but not the free electrons.
So, why do those electrons not those burn us? The answer is that they do not have the necessary mass. That transforms the cold fire into an excellent sterilizer, destroying viruses and superficial bacteria without burning material.
However, the experiment from the first video is at room temperature. So how do we create cold fire that freezes what you touch , the solution is to drastically reduce the temperature of the gas.
This situation opens a whole range of possibilities, but The Action Lab channel followed the dry ice routine, placed on a copper coil.
This causes the helium temperature to drop to degrees Celsius. Liquid nitrogen is commonly used as a refrigerant due to its very low temperature, food freezing, storage of biologics in specialized freezers and thermal grain refinement in metallurgy are typical however it is most commonly used as an efficient method to store or transport gaseous nitrogen.
Dry ice while not nearly as cold serves as a method of shipping frozen goods because it can stay cold for up to 7 days in engineered shipping cartons. Dry ice is also used in the food processing industry to prevent spoilage during large scale blending or grinding processes such as hamburger production, dry ice pellets are added directly to the grinding process to keep the temperature of the grind below the bacterial growth temperature range, liquid nitrogen is usually too cold for these applications.
CryoCarb is the leading dry ice manufacturer in northern Illinois and southern Wisconsin. We provide dry ice solutions for commercial and retail settings that are safe and easy to use.
