Why don't chemists add more powers of P and V? The bigger the odd polynomial, the more accurately we'll approach the actual experimentally obtained curve.
In theory this is correct, however the equations become far more complex when expanding to higher terms. Also these types of calculations are typically run on a computer so computational cost becomes a factor. You always want to balance accuracy with computational cost. Usually truncation at one of the first few terms gives you a nice trade-off.
Noted. I work through examples with my students in class so these videos are meant to be more topical. Next year when I have more time I may add more videos doing problems.
Ty, I'm here bcuz i need supplementation for my thermodynamics class. silly question but we don't use the v bar notation. OR i haven't seen it as a notation in my book. Could you let me know what it stands for? I do see my book using B prime B' etc. I'm using intro to thermodynamics by van ness et al. Im going to take pchem in the fall
You are DEMIGOD to me,just wen I needed an explanation for dis ,God bless ur mom
You explained it way better than my professor whos salary my tuition is paying 😂
This helps so much professor, greetings from Indonesia!
Pretty sure this is a dumb question, but why is the volume expansion inverted while the pressure expansion isn’t?

@@ProfessorDerricotte Thank you
Thanks Sir for your explanation.
It's would better to have examples also, problems to see how can we use the equations, thanks 🌹🌹

How can you write Z= PV/RT
in expression of Z ,V IS volume of real gas,so Z must be P(V-b)/RT.
correct me if I am missing something .
Thankyou
Thanks for the explanation, sir
Great explanation!

V bar is the molar volume. V bar= V/n
V bar is molar volume. Volume per mole of gas...
