Hi. I need help for making a procedure on an experiment about fire extinguishers.?

Question

The problem is: How does a fire extingusher work? The materials are supposed to be clear pint or quart bottle, baking soda, thread or yarn, match, cork stopper, paper napkin, cloth or towel, vinegar, spoon and cup for measuring, and a candle. It's due tomorrow. So please help. Any suggestions will do!!!

Answer 1

there are actually different kinds of fire extinguishers because there are different kinds of fires and ways to put them out. for example you would not want to dump water on a grease fire because oil and water do not mix and it would just cause the burning grease to spread!

some chemical means extinguish the fire by "suffocating" it, as fire needs oxygen to "breathe" so many combinations yield an excess of CO2 at the expense of O2 and so that is a popular method, especially in computer labs/electrical fires.

you really need to do you own research. get on google man, or read a book!

Answer 2

The four way's a fire can be extinguishd are:

-Reduction of heat

-Removal of oxygen

-Inhibition of chain reaction

-And removal of available fuel

To reduce the heat you could pour the vingar on whatever you have burning.

To remove the oxygen, place whatever you have burning in a container and cork it. The fire will burn up all available oxygen and die.

To inhibite the chain reaction of the fire you can light something and smother it in baking soda.

To remove the fuel, I'm not sure how you could demonstrate that with what you have. Perhaps light the yarn on fire, let it progress for a moment, then cut the yarn off ahead of the fire.

Hope that helps.
