The Joule-Thomson effect
zhlédnutí 4,9KPřed 3 lety
This video describes the Joule-Thomson effect in the context of the variation of the enthalpy with pressure. It showcases an isenthalpic process that allows to determine the Joule-Thompson coefficient
The variation of enthalpy with temperature and pressure
zhlédnutí 2,3KPřed 3 lety
This video describes how the enthalpy depends on temperature and pressure. The Joule-Thompson coefficient is introduced.
The variation of internal energy with temperature at constant pressure
zhlédnutí 2,1KPřed 3 lety
This video describes the variation of internal energy with temperature at constant pressure. The expansion coefficient and isothermal compressibility of substances is used to establish universal relationships between the heat capacities at constant pressure and volume. There is an error in the definition of isothermal compressibility at 8:50. Kappa_T=-1/V(dV/dP)_T rather than -1/V(dV/dT)_P. Tha...

Thanks! So helpful
This is a very high quality video over here!
I wonder why you stopped making videos...
Thanks sir i was so confused about how the entropy part cancels out but you helped to talk about approximation most pople just said in equilibrium entropy change is zero but jere we were talking about stantdard change in entropy
❤🇧🇩
6:45 MANNN i was so confused, my result was wrong since in the lecture notes of my professor this was not mentioned but assumed. Ty so much
Is that the acivity koefficients for both ions? thank you for video
Thanks so much for this video! Neither my prof nor my textbook could make me understand this concept, but your video really really helped!!!!!! :)))))))
Support this channel by 'NOT SKIPPING ADS". 🙂
I'm preparing for my Chemist Licensure Exam this coming October. I found your videos really helpful!
Well-explained. 💯
he is underrated
Really enjoyed the lesson, it was well explained 😊
Another underated channel sir.
very nice explanation
GOAT
i always feel lost in thermodynamics. thanks to you, you literally saved me. you are a great teacher!!!
Finally, I understand why we use deltaU=qv when the process is even not carry out at constant volume❤
thank you
Amazing explanation ❤
Excellent explanation indeed! May I know about the reference books?
Thank you!
you did it wrong, idiot
wow
Great explication, thank you
You're the best!!!!! Thank you (':
thanks. this really helped with my assignment. ❤
te quiero
Thanks. That was a helpful 😊
Crazy good
Very underrated channel <3
do we have to assume that the volume is changing at a constant rate? could the volume change at an increasing rate?
thanks a lot .........from sri lanka
tanx
U deserve million s of likes and views
Excellent! Thank you!
What molecules are those} ? And are those dotted line hydrogen bonds?
Tq u
Hello, What is pseudo-zero order ? Can you explain it briefly,thanks a lot.
You explain in an amazing way ❤
Instant sub -- excellent lecture
outstanding explanation -- I had never seen a VB MO diagram for the simple acids, excellent -- does the presence of nonbonding orbitals in any way effect the pKa of the acid?
Thanks a lot for the video
@ 2:55 In my imagination, going for 1s to 2s the distance between the electrons is increased and thus the dipole is increased. Where am I going wrong here?
great lectures sir.. I wonder if you kept uploading lectures
6 years later and still saving chem student lives
Thank you ❤
awesome vid :D cleared up so much in so little time
Thank you 🙏
It is a difficult concept but you explained it beautifully.
