I believe that smoldering means that the reaction is progressing slowing, not producing enough heat to create flames. Addition of [itex] O_2 [/itex] could change that.tony873004 said:On a related note, what's the difference between something on fire and something smoldering?
If a log is in a campfire, it can either burn (fire) to ash, or smolder to ash. But it seems like fire is more than just heavy-duty smoldering. When the breeze blows, sometimes smoldering things catch fire. And often there's a sound associated with this.
Also, when you blow out a candle, sometimes the wick continues to smolder for a few seconds.
Does smoldering require oxygen like fire? I guess I could test this myself
I would call hot, glowing combusting gases 'flames', and hot glowing combusting solid carbonny stuff 'embers'.tony873004 said:On a related note, what's the difference between something on fire and something smoldering?
Yeah, it's still hot. Being solid, it takes longer to cool down than the gases, which are quickly cooled and dissipated.Also, when you blow out a candle, sometimes the wick continues to smolder for a few seconds.
You certainly need oxygen to have a fire. If you have no fire, you have no heat, and therefore you have nothing to make the embers glow. However, if you remove oxygen from a fire, the embers will continue to glow, but will cool down until they stop glowing.Does smoldering require oxygen like fire?
