Entropy and Second Law of Thermodynamics (1)

[Phil290694]

is there only one girl in the class?

[djpiyushkant]

u r great sir

thannk u

[Guinnie]

good video

[sharif958]

take too much time to express and always with a lack of preparation.

@sharif958 go fuck yourself

[sharif958]

i am disappointed this types of weak lecture with some wrong information.

[90oooo09]

@sharif958 He is giving his time and effort to teach us a concept that is otherwise difficult to grasp. You should be very thankful and appreciative, not critical.

@freelanceteach Thank you for these videos! They are very helpful! Your pacing and repetition is excellent for reinforcement! I am finally understanding concepts that I was unable to grasp in college lectures! You are a great instructor! Thank you!!!!

why he's hitting the chalk so hard :P

All that the second law means is that in terms of energy a system will destroy more molecular bonds than it will create. Otherwise you would have a system that could create more energy than it uses in creating that energy and you would have over %100 efficiency in the system. Energy cannot 'concentrate' in a system it must 'dissipate' Thermodynamic disorder must always increase.

Henry Poincare named the conception of "entropy " as a " surprising abstract " Lev Landau wrote: " A question about the physical basis of the entropy monotonous increasing law remains open " One physicist said : " The entropy is only a shadow of energy“ # History of Entropy 1 - Clausius : dS= dQ / T. 2 - Boltzmann : S= k log W 3 - Planck : h*f = kT logW # The formula of Entropy is : h*f = kT logW Israel Sadovnik Socratus

he is the best ever, a good example how teachers should approach to the students, interactive class, so you are sure u have learned something today

[ghosty1490]

p.s not saying hes greedy or swindliling ppl just saying that does help ;)

[ghosty1490]

ah smart cookie filmed the teaching in his class so he could put it on his pay what u want thingy for an extra bill or 2. i have no idea what hes talking about i just came apon this vid but i still think the most importen thing u can learn hear is ...money

less work+more $+ alittle greed&swindiling= happy :)

[girlie786]

Thank you, sir, for making me understand the dependence of "change in entropy" on T... It now makes pretty much sense to me... Thanks a LOT..!!!

[girlie786]

@topbluffa1: lol.. i, too, was thinking that!!!



[Phacix]

this classes are for chemical engineers? or any engineers?

[letsgosurfingdude]

Your Hot! Girls really do like smart guys.

[topbluffa1]

does this guy have only one person in his class?

[merijn119]

than your teacher sucks big time!

He needs 10 minutes to explain nothing

[ELMahdi1993]

THIS GUY IS THE FUCKInG BEST THING ON EARTH!

[ktcg05]

u explain better than my physics teacher!!!!

[raider968]

I don't know why I spend an hour travelling to university anymore :O

[mpdp85]

man can u please make videos on valuing pension scheme benefits, paticulaly on the use of commutation functions and the use of multiple state markov models thank you (will pay)

[fawad228]

i m gonna donate :)

I've always seen P on y and V on x -- in school books, online videos, online resources -- never the opposite.

[GigaFro]

Your pv graph is backwards... The P should be on the x axis and the v should be on the y axis. Perhaps something to consider for consistency.
