Melting a tree to ash

[PimpDemon]

How much energy is required to melt a average sized tree into dust in seconds?

 

[ShadowSythez]

Uhm. I think the calculation is pretty simple, you need these things:

.Volume of the tree

.What wood the tree is made of

.The leaves of the tree are almost impossible to add on so I would ignore it

Lets say your talking about a large black oak tree, I used this calculator and got 60900 cm^3

Pulverisation of black oak = 44.9538 J/cc

60900 x 44 = 2.6 megajoules

I think this is how you would go about it. I may be wrong though

Its most likely better than anything i could do

You can't melt a tree bro, it's carbon, it skips the liquid stage straight into ash.

Yeah this is wrong, turning to ash explicitly requires heat AKA you'd need latent heat and specific heat capacity for this, not pulverization.

I have trauma from specific heat capacity calculations ):

Thats talking about vaporization which is turning something in to nothing but vapor which is not the same as turning something in to dust.

Just find the temperature required to reach char and swap it in with the vaporizing temperature. Problem solved.

Would it though? I mean chared tree isnt actually dust. its just a very burned tree?

Same principle, heat is involved.

Alright

I've always used energy density for burning trees to ashes.
Reducing it to char is moreso turning it into charcoal instead of complete ash, which takes WAY less energy to do.

Since charcoal has a lot more available energy to give than ash, which has next to nothing; you can use charcoal as fuel pretty damn easily...but using ash as a fuel source? That's not gonna happen that easily.
Char and ash, are completely different things. You cannot use "charring" as the same thing as reducing something to ash.

So to "reduce it to ash", you must expend all (or nearly all) available energy in the substance itself that it can give rather than reducing it to char (which still has quite a large amount of energy left to give). And not to mention...what do you get when you burn charcoal? You get ash.

Now yes, energy density does vary depending on the wood type. It ALSO depends on if it is green (alive or recently cut), air-seasoned wood, or kiln-dried wood.

But there is an approximate energy density for most wood that I found on a Canadian website about wood heating:
Green: 10 MJ/kg
Air-Seasoned: 16 MJ/kg
Kiln-Dried: 19-20 MJ/kg

As an example:
Lets assume a live, 10-ton tree.
We would use green wood as it is alive.
10,000 kg x 10 MJ/kg = ~100,000,000,000 joules of energy the tree has available.
Which is around 23.9 tons of TNT's worth (8-B)

But unless you reduce it to ashes in a literal second, you would not scale to the entire available energy;
Say it took 10 seconds to reduce it to ashes, you would then scale to a 1/10 of that value; 2.39 tons of TNT, or a bit over baseline High 8-C.

BTW, this should also apply to cremation as well.
As cremation turns a body into ash as well. Not just merely charring their body.
As again...char and ash? Completely different things. "Reducing to ash" is a level beyond merely charring.

Alright cool thanks btw if someone fires 5 Blast each blast turns a tree into ash and another character punches is equal to the combined power of those blast he would have 5 times the power of a blast right?

Yes, if the punch is stated to have the combined total of five blasts.

Awesome
