"second most famous adolf" LMAOOOOOOO
Completely necessary commentary
1st most popular
Who's 1st?
@@changsina6893 ww2 german dictator adolf hit-er
@@changsina6893 Hitler 😂
These videos make me question why I am paying my school fees
Good question 😉
You need to be able to show proof that you know all of this stuff to get a job. Although some universities have such bad grade inflation nowadays.
Same here
If something sounds hard and you pay for it, and very little effort is put to explain it clearly , it probably gonna make it "important" , and so it is required ... You see my point?
This was fickin' awesome!
To make it works you have to make the wall less thick. Less fick!
The clearest explanation I’ve ever been exposed to👌 thanks a lot
Extraordinary way to teach a law hand off to that professor
You pronounce Fick with emphasis. In Germany everyone would chuckle ;)
Bro just hit's on a girl's with his pronunciation.
Wow this is so clear...I was totally lost at the lecture today..your video really helped me alot
I really appreciate the way u made me learn this typical stuff.. Thnks! keep uploading such ideas!!
Gosh my books are useless compared to this
me too bro
now I finally understand what my book was trying in vein to communicate to me!!
Thank you so much for making all of these brilliant videos! Have a great weekend!
Bingo, I will never forget this analogy, they way you convey this is just invincible....
10yrs later and it's still one of the best vids out there....wow🎉
What an amazing video and explanation, the game example was a really creative way to tie the concept to the equation.
Love the video! Thank you. Great teacher
beautiful drawing and exact perfect timing with verbal explanation! what is the drawing tool used?
well done guys...a great basic treatment (from a teacher)
I LOOOVE YOUR VIDEOS! GOD BLESS YOU AND YOUR CHANNEL~ :)))
amazing video just amazing ...you freakin' helpend me a lot thank you man!!
Thank you. great explanation
very beautiful explanation, i appreciate your job sir
thank you !
can u make a video about Noyes- Whitney equation please? :)
Great explanation!
Very nice!
It's very helpful
That was AMAZING 👏👏👏
just brilliant wow .. thank you ..!
Great explanation! The formula on wikipedia is so difficult to understand :s
thanks so much! This really helped :)
i love you man. thank you so much
very helpful!
Very helpful 😇😇 ty
excellent visuals!!
Dude. You're my favorite Khan out of all Khans! Please make more on the respiratory physiology!
He is a Desai not a Khan
this is amazing!!!!! Thank you sooo much!
nice presentation.. ficks law
Great video,your awesome
You might also use a check valve concept, where once a particle gets a certain distance, it can't go back, 4:11.
My first thought was to heat it up! but I'm coming from the material science side of things. when in doubt heat it up or cool it down!
I m waiting for the second law !!!
Adolf Fick or translated from German: Adolf FUCK 😂😂😂😂 as a German this was the best video I've watched for some time
I am conducting water barrier testing of a nanocomposite as per ASTM D570. Basically immersing the samples in water and testing the weight regularly in order to draw the graph of percentage of relative mass uptake vs. square root of time and ultimately calculate diffusion coefficient. Now, the ASTM standard asks us to maintain the thickness constant at 3.2 +/- 0.3 mm. Why so ? If Diffusion coefficient is a constant why thickness becomes so critical.
good video ... i have doubt....i read in treybal that ,if pressure is decreased diffusion will be faster,because the no. of collision encountered by the molecules will be less..so the molecules moves faster ...plz help
AMAZZZZIINNGGGG~~~~~
Very nice
does khanacademy educate on voce acting?
Does the solubility in D refer to the solubility of the gas in that wall/membrane or in the sides/liquids around it?
LoL, my idea was to make a vacuum on the other side...
nyc 1
Thanks so much. Easy to understand!!!
Thankyou
do u use bamboo wacom ?
Sorry I got confused! Isn´t the equation you are talking about Nernst equation. And Fick´s equation is flow= uptake/ A-V?
Yes
cool
I think it's suppose to be T^2 in the denominator
Wheres our $5????
why there is no mention of flux at steady state ?
where the D constant come from?
Great video sir. but, please avoid using red color due to its less visibility over black.
Keep your stupidity to yourself
Just in changing the size of molecule the chemical design of life becomes more obvious.
that "pressure" is very misleading
👍
Blazen92 "like Einstein said if anything cannot be simply explained then you don't complete understand the concept."
would increase in temperature help?
That's my question too
are the molecules inside the box or out someone plz answer
Buy the Way Fick means fuck in german. Made me had a very good time while learning physics :D
It makes you think like a fick! GENIAL
+Victor Gabriel Silva Cardoso it actually means what you think in german
yes, the use of the word schootch is very scientific, i love it
The equation’s notations used here are very limited and can be misleading. T should be reserved for temperature. Concentration is better than pressure.
can't forget about Adolf Dassler, infamous founder of Adi-Das!!!
Why the temperature doesn't effect the equation
who is the first well-known adolf? adolf mayer (the founder of the idea of bactery) or the other adolf?
Adolf Hitler
Fick means Fuck in German
+ASIT CICI well then Fick's parents are such a good trollers
👏👏👏👏👏👏
Amoont, hehe canadian eh?
Increase temperature
Anyone else learning alveolar gas diffusion here lol
Dominick Guerra haha me 😛
sup guys, same here lmao
I thought flux was that thing you put on soldered wires
Can someone from Germany explain to me why his family name is so ..Fick, sau geile Nachname
Amoont.
I F U K I N G L O V E Y O U ASFJDYDUAYSGDA ♥
Second most known Adolf in history. I love the wishful thinking, that era has past 😅 unfortunately. Adolf Flickher could be a way to memorize it.
"the second most known adolf in history"
This is stupid. why am i paying money to go to college. you just explained something perfectly in about 10 minutes that my professor could not in one hour
Why doesn't increasing the temperature increase the rate of diffusion?
It must be because he's from the medical profession, as a Materials Engineer, thermal diffusion is the most important variable.
Well, actually, it does increase the rate of diffusion. What do you know from ideal gas laws? How is temperature and pressure related?
Wooly Tomcat It does, but not anywhere close to the temperature differences discussed here, if you were doping a silicon wafer with germanium for example, the differences in diffusion due to temperature is very small on a per degC basis. However if you started diffusing at 0.1*Tmelt, and then compared it to 0.5*Tmelt, you would notice a considerable improvement.
-D=dc/dz ! this the law !
Please explain in Hindi
I should have been homeschooled
I think you spell amount wrong
Bros gonna get copyright ban from hitler. LMAO
1:26 come on man, ammont??!
Hamed H come on man ...stop being so picky & just learn.
amoot
sweetie thats not racist
RIP headphone users....
I wonder what fick means in german! Lol
lmfao
it is a box or a wall wtf
Your brain is a thick wall
Adolf Thicc
shitty school..
waste of time
what is the indirect racist remark in the beginning of the vid good for???? the 2nd adolf is not worth mentioning in any context ever... especially not in a study tutorial
plz edit this..
