Adiabatic Change and the Second Law of Thermodynamics - University Physics

[@matthewtaylor445]

This series as a whole is incredible! In 2 nights I went from someone who got a bad lecturer in first year thermo and permanently put off any ambition to learn the theory, this has changed that to someone who is enjoying learning all these things I wish I knew in the first place! Amazing videos so far!

Thanks, honestly really great stuff to hear!

Thanks for this playlist man. As someone dedicated to mastering the highest levels of physics through self-study, this playlist is a godsend. You're awesome.

fantastic series :D

thx so much for this playlist

I'm really loving this series. Do you have a recommendation of a text book that covers the topics in a similar way?

[@pazzy768]

I actually got this information from my lectures, but this information was mostly based off David Griffiths’ ‘Introduction to Electrodynamics’ which is pretty much the template that most university courses follow!

[@mikep8857]

@@pazzy768 Well I certainly wouldn't have thought of looking for information on thermodynamics in an electrodynamics book!

[@pazzy768]

@@mikep8857 sorry, my bad!! (I’m doing the electromagnetism course at the moment!) The textbook our course used was “Thermodynamics and Statistical Mechanics” by David Goodstein.

What does Entropy has to do with Quasistatic.? Isn't it that the term "Entropy" is focused on disorderedness of particles.?

[@moosasaghir]

Hi, great video! I had a question though - when you use "quasistatic" in this video, is this the same as being reversible? I would think that a process that happens very slowly such that the system is in equilbrium at all times would be reversible?

[@pazzy768]

Hi, thanks! I don’t think they’re quite the same thing. Quasistatic refers to the system being in constant equilibrium with its environment, and that you’re changing a parameter slowly enough so that the system and environment are never unbalanced. However once you’re getting into reversibility then the second law of thermodynamics would start to kick in, which is non time symmetric. Technically you can go back and forth along the same part of (eg.) a Carnot cycle but in reality the efficiency of that process will never be more than the ideal efficiency, which is already less than 1.

0:45 You meant delta Q =0.

[@pazzy768]

True!
