Fick's First Law

[@jeevan999able]

This prof is a legend

[@JH-KU]

Thank you for the excellent explanation. I appreciate you took time to connect the 1st Fick's law with the previous "related" laws. This gives students the bigger-picture without first diving into the detail. Thank you again.

Here is the difference between an IIT Professor and the others.... An outstanding teaching skill. 🙏🙏🙏

[@Unknown-qg9nj]

😂😂😂 no lol. that's a completely wrong statement. This prof is an exception. Most iit profs have absolutely zero teaching skills

Couldn't the negative sign on these laws be indicative of the fact that one quantity decreases with respect to an increase in the other as time goes by? Clarify. Otherwise thanks for these insightful videos professor.

[@rajeshprasadlectures]

The negative sign is just a convention based on our desire to keep the diffusion coefficient a positive quantity. Note that j and dc/dx have opposite signs. If dc/dx is positive then j will be negative. So if we write the relation as j=D dc/dx we will have to make D negative. Nothing will go wrong if we did that. We will then have to live with the fact that D is negative. Founders of our science decided that it is better to keep D positive and so inserted a -ve sign in the equation j=-D dc/dx.

[@karanthapa1127]

Great Job as usual.

Sir in that lnD Vs 1/T graph 1/T =0 mean that T=Infinite . Can absolute temperature be infinite? Which mean that at T=infinity »D=D°

[@introductiontomaterialsscience]

Practically you cannot have infinite temperature. Stil, as lnD vs 1/T fits to a straight line, its intercept can be determined by extending the line to 1/T=0.
