brief observations on fires
>1:Once a substance is ignited it cant be set on fire again

>2:fires spread based off their temperature, the hotter a region is the faster the fire spreads


>3:Objects will increase in mass after being set on fire


>4:an unbreathable smell will be created after an object is set on fire


>5: fires are observed to die when covered with something with alot of mass even if it is flammable


hypothesis
>1a: the reason why you cant set a burnt object on fire again is because the substance has already reacted with its environment in a matter that it cant produce an exothermic reaction again

>evidence: when I put an ignited match in water 5 times the fire on the match went out 100% of the time and couldnt be ignited again


>2a: fires spread in volume based of their temperature


>3a: fires form when a substance,combines with oxygen(or another substance that triggers an exothermic reaction) and begins to break down and release massive amounts of energy towards its surroundings in the form of heat, when this happens a chemical reaction occurs and thus the ignited substance reacts with the substances around it to form compounds thus forming substances with heavier masses than the substance before set on fire


>4a: a human being cant smell anything other than oxygen contentrated in nitrogen meaning when a substance becomes ignited it forms an unbreathable substance naturally through a reaction


>5a: thats simply a biproduct of resistance towards a force, if an object with alot of mass overcomes a force it simply will not move, likewise if a fire tries to cause an object to react its temperature needs to be high enough that the molecules surrounding the fire create a force strong enough to generate a reaction otherwise no reaction occurs, summarized: a fires temperature and mass will determine how much resistance it may overcome in order to ignite its surroundings, hotter and heavier fires can burn more flammable things, smaller and cooler fires cannot



<ideas on fires

>A fires rate of expansion(expansion distance per second) is based off the force of attraction between molecules that trigger the exothermic reaction that causes a fire to form

>fires naturally diffuse and spread faster and faster as there surface area increases over time and the amount of substances becomes accessible to the flame again increases over time


>how much a fire can burn is based off how much energy the fire can utilise to do the work required to trigger reactions


>condensed flames are hotter and can burn more flammable objects because molecules within the igniter(the source of the fire) have less space to diffuse and likewise collide with each other more rapidly leading to increased amounts of pressure and therefor force at the expense of size

>The story is told of something Heraclitus said to some strangers who wanted to come visit him. Having arrived, the saw him warming himself at a stove. Surprised, they stood there in consternation – above all because he encouraged them, the astounded ones, and called to them to come in, with the words, “For here too the gods are present.”

>But he had himself withdrawn into the temple of Artemis in order to play knucklebones with the children; here, the Ephesians stood around him, and he said to them: “What are you gaping at, you scoundrels? Or is it not better to do this than to work with you on behalf of the city?”


pls pretend artemis still has her arms and she's holding a torch and a harp

I don't buy that an object has more mass after expelling clouds of smoke. I can buy that many objects will be denser, i.e. have more mass per unit of volume, but this will not be true for all objects.

I don't think your statements about what human beings can breathe and smell are correct. We breathe and smell a lot of things.

I recommend reading Notes From The Holocene by Dorion Sagan, I think you'd like it.

yeah but some of the burned reactant is turned into gasses
isn't it literally like carbon + oxygen -> co2 + h20?
these things leave the original object.

Introducing the Waste Not Wood Ash workshop series where the Living Web Farms biochar crew takes a deep dive into understanding applications for one of our most common everyday waste products. As we deal with ashes from the last wood stove season and prepare for the next, discover practical everyday uses for wood ashes you can use year round. We’ll also explore the science of how and why wood ashes work in the garden, as an ingredient for natural soap making, or even as an ingredient in natural building materials. In part 1, Dan begins by filling in some of the gaps in wood ash research and sifting through some of the more and less useful info found on the internet.
If you have more clever ideas about how you use wood ashes around the farm and homestead, please share them in the comments below.
