Blue fire = gas fire?

MagnificentOne - 2006-11-04 20:23:00 - Chemistry

I know that when burning organic materials fire can only be red, orange, or yellow, but are blue fires always gas fires? If it isn't a gas fire can you put out a blue fire with a lot of water?

Mejor respuesta:

Yes, and yes. When organic compounds are burnt, their combustion reaction usually yeilds a range of colours from red to yellow. However, when hydrocarbons such as methane or ethane are burnt, their combustion reaction produces sufficient heat to produce a wider spectrum of colours such as blue. A combustion reaction occurs when sufficient heat is applied. If enough water is added to reduce the temperature to below that which produces the required activation energy (that is including the actual compound and its environment), then the flame will go out.

Yes Blue flame is gas fire.

blue flame basicly only occurs with materials like gas since most things dont burn as hot, but im pretty sure its just that once it hits a certain tempature it is blue instead of red fire

blue = gas......... gas and water do not mix............
