Thermodynamic Connection (Pressure)

A thermodynamic connection formula allows us to calculate the pressure directly from the partition function.

recently transitioning from organic synthesis to computational chemistry, these videos really helped me to learn the fundamentals of statistical mechanics and thermodynamics. Thank you!

[@PhysicalChemistry]

I'm glad to hear the videos are useful. Welcome to the dark side!

[@tsotnedadiani7407]

thank you very much for all your effort. these series are great. please cover whole surface science

[@PhysicalChemistry]

Thanks, I'm glad you like them. I don't have any plans to do many surface science videos, unfortunately

[@tsotnedadiani7407]

@@PhysicalChemistry That is perfectly okay , hope to come across with you on some conference maybe to thank you in person

[@hindh2451]

Thanks a lot I really enjoy watching your explanation. I plan to finish all playlists in your channel.

[@PhysicalChemistry]

That's two full semesters of PChem, if you watch them all!

Dear Prof. Thank you for uploading such great lectures, I really enjoy these and like your teaching style.

[@PhysicalChemistry]

Thanks, I'm really happy to hear that!

Thank you for the great lecture. One question related to the term E: can you just interchange the term of work to E in microscopic level? As the equation of F * delta l is work in classical mechanics. Thanks a lot!

[@PhysicalChemistry]

Yes, that's right. The E under discussion @2:44 could also be called work. That "side" derivation is an attempt to show that not only is it true that w = F Δl, as you already know, but also w = P ΔV. That relationship between energy (in the form of work), pressure, and volume is more intuitive at the macroscopic level, but it is also true at the microscopic level. And that's the main result I wanted to be able to use to derive the thermodynamic connection formula for P.
