Can blood extinguish a fire?

Can blood extinguish a fire?

it's >50% water, so I assume yes

Any substance that can effectively deprive fire of oxygen can extinguish it.

Think of it in terms of physics, a fluid such as water or blood basically function as a three dimensional blanket that chokes the fire out and prevents the reaction from continuing.

blankets are three dimensional already :^)

Yeah I know I'm just trying to help OP visualize how water extinguishes fire

not exactly.
Water cools down fires very effectively (high heat capacity and evaporation enthalpy) to the point where the spontanious reaction of the "fuel" with oxygen is no longer possible.

For oil water is a very poor estinguishing agent, since it will just dropp through the oil to the bottom or even disperse the oil through fast evaporative expansion.

yeah sorry pal i was just being a narrow minded ass

Right, that's the mechanism of how it deprives oxygen from the reaction, which is still very much a physical phenomenon.

Yes it wouldn't work for oil because of its hydrophobic properties, that's a good point.

heh no worries I actually expected your exact reply after writing that phrase.

>Any substance that can effectively deprive fire of oxygen can extinguish it.
is true, but not how water works on fire

gets it right
