It's been a while now since I made calculations like that for far less interesting chemical processes, but I'm pretty sure that
is not the case, unless this human combustion device has a built-in high-end air compressor in it.
On the other hand, my guess is that a sudden release of 157 kJ would be enough to burn the cat's hair. Let's say the chemical reaction takes 0.2 seconds to complete. That would be an equivalent of 785 kiloWatt released (157 kJ/0.2s). And since the energy should be very concentrated on a small volume of air before it dissipates through the room, assuming 157 kJ is correct, my guess is, that it would burn through the cat's hair.
Poor cat, though.
Also you converted kJ to calories and then used the resulting value of 37 to apply it to air. Calories are defined by the specific heat capacity of water. Specific heat capacity of air is approx. four times less than of water which would result in a temperature increase of about 150 K.
The specific heat that I found for hair though was in calories, hence the conversion. Another problem with your assumption here is that you assume a rather static environment where the cat would feel all of the energy but as seen in the video the cat wouldn't be in the entire burn.
You may be correct that 78.75 ml of hydrogen isn't 0.657 kg (as I used an online converter and put in atmospheric pressure for the pressure and 300 kelvin for the temp) but I may have done something wrong (again 2 AM calculations)
While I definitely agree my calculations are certainly flawed somewhere (chemistry is honestly one of my least liked subjects) I will definitely say that if you can find flaws in this than write a post debunking my post and correct the answer and you will get some pretty hefty votes from everyone! I apologize if my correction at the top is condescending, I have difficulty with tone. But we also have to keep in mind that this, by no means, is taking account the amount of burn or the fact that most farts are released over a period of time and usually aren't instant.
Ah, now I understand. (It didn't sound condescending, btw. I hope I didn't either). I still think you would have to give more weight to the spec. heat capacity of air because it is the transmitter of energy until it reaches the cat skin.
The conversion of hydrogen volume to the amount of hydrogen goes through the molar volume of an ideal gas which is under normal conditions 22.4 liter/mol. (0.0785 liter / 22.4 liter/mol) would give us 0.00325 mols of hydrogen. Maybe the converter you used was working with cube meters or something?
Nah, I am not going to make a post :-) Chemistry and physics are way too far back for me.
Now, I am thinking that this guy might have sucked in some lighter gas into his rectum. Some people can fart at will.
No you didn't sound condescending, sorry for the late reply. School just started up along with some other things.
If there are 0.00325 mols of hydrogen as stated then the energy released by the hydrogen would be 1.57 kJ instead of 157 kJ thus reducing the temperature even more. I do apologize if my conversions are incorrect and will make the note.
Please turn that into a more comprehensive post
Alright guys... Challenge accepted.
Please take the challenge seriously and don't dissapoint us!
I really did:
https://steemit.com/science/@replichara/the-fart-fire-burn-cat-video-debate-continues-a-response-to-trumpman-and-kryzsec
Steemit needs more fart science. I am dissapointed with your findings. Hopefully @lemouth, our fart expert, will debunk your debunkment and prove this is actually possible. Fingers crossed
Well I am looking forward to see if LeMouth can debunk me, I will accept someone proving me wrong
especially about this subject
Do you really want me to put myself a probe on??? No way!
I don't make comment on farts! :D
This is just exactly why I love this platform. ow man this made me laugh so hard even after reading it the second time on here. 😁
t.
Well I am glad you enjoyed it, its a good breather from all the drama on steemit right now!
Haha, breather. nice one.
Also, what is the drama, you mean all the same posts saying we are going to the moon every day with the steem price, and not actually good content is provided haha? 😂
Or am I missing something here.😘
t.
Interesting! well done prof @ kryzsec, waiting for prof @lemouth though.
I am too! I really enjoyed writing it and am glad you enjoyed it!
You can wait... my thought won't come. My definition, I don't comment on farts ;)
Congratulations @kryzsec, this post is the fifth most rewarded post (based on pending payouts) in the last 12 hours written by a Superuser account holder (accounts that hold between 1 and 10 Mega Vests).

This is so good that I will re-steem it on Facebook
Haha thanks!
Ahahahahahahaha! @lemouth was the fart-science thing inspiration and I love how it's spreading :P
I like fart-inspiring people :)
Well it was fun to post, though lets see if @lemouth can debunk me!
Fuck yeah fart science! <3
One of the best kinds of science! I mean its debatable on what the true best is.
Debatable!? DEBATABLE!!!??? Thats, the last straw, if we cant even agree that fart science is the premium of all the sciences, then I see no further point in continuing this conversation... /s
Well there is also the following: poo science, sex science, genital science, science of things that go kaboom, etc.I am definitely saying that fart science is p there but not 100% certain it is the top,
Okay, you make a fair argument... ;) Just so long as you arent one of these crazies going on about physics or any of that crap... :)
Of coarse not! I could post about engineering but I would rather post about burning farts!
This is the reason I joined steemstem in the first place. It was the most likely place to find such answers
Well trumpman said yo own a cat and are supposed to about testing this experimentally, my hypothesis (from 2 AM) is that it won't catch fire. And I mean doesn't this prove that steemstem > stack exchange!
So...basically you're saying that before these vids, these guys shove some kind of flammable liquid up their ass? Eww. It just became grosser.
Or on the cat... but for it to be true yeah....
Well interesting post
it is interesting to read an I like the science behind the topic
I like it as well
I am glad you liked it, its supposed to bring some light to the steemit science!

good post.thank you.
Tanks for the support!
i love it, man...
Glad you do,
I hope someone proves you wrong.
In some ways I do too, but at the same time I hope not because otherwise they then would have the potential to have actually lit that cat on fire.
I am ok with a singed kitty... for Science.
Just some fart science LOL
One of the best!
Very nice post its awesome keep posting
A little generic of a comment bt I will always keep posting
Good post 👍👍👍
Vague and generic comment, a better one wold receive an upvote
good post!!
