well the tank that holds the foam is compressed with co2 but what actually makes the foam is the nozzle it acts as an aerator and thus making the liquid into foam
-----------------------------------------
Air is the most simple example of gas used in foam fire extinguishers.
which gas helps to make the foam that firefighters use
Air is the simplest example.
CO2
fire retardants used in the foam are trimethyltrimethylene glycol and hexylene glycol.
i think... water hose fire extinguisher sand CO2 Gas Foam just a guess :)
Yes glue is a mixture, and it is also a solution.
AFFF or aqueous fire fighting foam is a chemical agent that is added to water usually at a rate of about 300:1 (300gal water for 1gal foam concentrate) this mixture is then mixed with the outside air as it exits the nozzle and creates a blanket of foam that suffocates the fire.
The same air that we breathe !!
Inside foam is a gas. :)
A well Control Firefighter is a firefighter who extinguishes oil and Gas well fires .. This site shows what the job entails http://www.wildwell.com/
Closed-cell foam insulation differs from open cell foam insulation in the fact that closed-cell foam insulation has tiny foams cells that are closed and packed together. They are filled with gas that helps the foam rise. Open cell foam does not have this characteristic.
In foam, air is typically the solute and the liquid or solid that surrounds the air bubbles is the solvent. The solvent helps stabilize the foam structure by forming a film around the air bubbles that prevents them from coalescing.
