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.

[@mohammadhafeezullah1846]

Same here

[@armitosmt5753]

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?

[@2357y1113]

This was fickin' awesome!

[@sarvenazkarimi8720]

The clearest explanation I’ve ever been exposed to👌 thanks a lot

[@guitarunique4592]

I really appreciate the way u made me learn this typical stuff.. Thnks! keep uploading such ideas!!

[@gabrielegiordano_channel]

To make it works you have to make the wall less thick. Less fick!

[@kkmham]

Thank you so much for making all of these brilliant videos! Have a great weekend!

Extraordinary way to teach a law hand off to that professor

[@Shacklebolt29]

Wow this is so clear...I was totally lost at the lecture today..your video really helped me alot

[@tmujir955]

What an amazing video and explanation, the game example was a really creative way to tie the concept to the equation.

[@Parisobserver]

Love the video! Thank you. Great teacher

[@lianedejager8808]

now I finally understand what my book was trying in vein to communicate to me!!

[@jollyjokress3852]

You pronounce Fick with emphasis. In Germany everyone would chuckle ;)

[@iamthestrongest007]

Bro just hit's on a girl's with his pronunciation.

beautiful drawing and exact perfect timing with verbal explanation! what is the drawing tool used?

You might also use a check valve concept, where once a particle gets a certain distance, it can't go back, 4:11.

[@sohamurali6949]

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

[@JohnKramer913]

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!

[@koruptxshun]

Dude. You're my favorite Khan out of all Khans! Please make more on the respiratory physiology!

[@ss-nu8xx]

He is a Desai not a Khan

[@Canyldrm3566]

does khanacademy educate on voce acting?

[@muraliishwar7022]

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.

[@D_kiki999]

AMAZZZZIINNGGGG~~~~~

[@kalyanjnc]

Very nice

[@lucyrodrigues7609]

Does the solubility in D refer to the solubility of the gas in that wall/membrane or in the sides/liquids around it?

[@difanasameddavood7363]

Thankyou

[@tariqmehmoodraza9961]

why there is no mention of flux at steady state ?

[@phindyp7308]

nyc 1

[@hunnyNur]

where the D constant come from?

[@fabiolapuga5764]

Sorry I got confused! Isn´t the equation you are talking about Nernst equation. And Fick´s equation is flow= uptake/ A-V?

[@MedicalBlackBook]

Yes

[@SaveTheWorldJD]

do u use bamboo wacom ?

[@hansudowolfrahm4856]

Adolf Fick or translated from German: Adolf FUCK 😂😂😂😂 as a German this was the best video I've watched for some time

would increase in temperature help?

[@fortnitekostyk6512]

are the molecules inside the box or out someone plz answer

[@davidwang6147]

LoL, my idea was to make a vacuum on the other side...

[@syranth8912]

Just in changing the size of molecule the chemical design of life becomes more obvious.

[@wadwans.9772]

Thanks so much. Easy to understand!!!

[@saas5633]

Why the temperature doesn't effect the equation

[@Dluv021]

Blazen92 "like Einstein said if anything cannot be simply explained then you don't complete understand the concept."

[@the9thGen]

that "pressure" is very misleading

[@jmisc]

The equation’s notations used here are very limited and can be misleading. T should be reserved for temperature. Concentration is better than pressure.

[@Cardboardbocs]

Amoont, hehe canadian eh?

[@adrianmaulanamuhammad7225]

who is the first well-known adolf? adolf mayer (the founder of the idea of bactery) or the other adolf?

[@Haixu_Wang]

Can someone from Germany explain to me why his family name is so ..Fick, sau geile Nachname

[@EpisisTune]

I think you spell amount wrong

[@shcsepac]

Why doesn't increasing the temperature increase the rate of diffusion?

[@jamessutton4809]

It must be because he's from the medical profession, as a Materials Engineer, thermal diffusion is the most important variable.

[@janlandau6226]

Well, actually, it does increase the rate of diffusion. What do you know from ideal gas laws? How is temperature and pressure related?

[@jamessutton4809]

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.
