I would have loved to see the rest of the tutorials on thermodynamics from chapter 9 to 12

[BloolpyGaming]

you're honestly saving my life!. I can't express how helpful this video is. THANK

00:05 Entropy is a measure of disorder and thermal energy.
01:41 Entropy of an isolated system always increases.
03:14 Cyclic integration of Delta Q over T is always less than or equal to zero.
05:18 Clausius Inequality: Reversible processes have Delta Q/T equal to zero.
06:44 Entropy is a new state variable discovered by Clausius.
08:37 Definition of entropy change in a reversible process
10:25 Entropy change in isothermal heat transfer process
11:46 Entropy change during constant pressure process

thanks for the help. just realized three days before the final that my prof sucks. this is a life saver.

Thank you so much for this excellent video. The way you related the little bits of knowledge together adds meaning to the topic and it is, therefore, easier to understand and remember

[SuperDunci]

Great video, i learnt a lot. I believe however you switched the impossible and irreversible equations around. It was written in my textbook (Moran's principles of thermodynamics) and I checked google as well to be sure.

Thank you so much this has been such a huge help

7:00 thus it is an exact differential in the reversible case

U said entropy is a measure of thermal energy that is not available to be converted to work.
Does it mean entropy is energy but useless.
Not the transferable one like the heat that is transferred from higher temperature to lower temperature?

Lower the entropy change higher the efficiency of the engine?

Is it true because entropy of the universe is increasing the entire energy of the universe should become useless one day.
Is it true because entropy is also a measure of multiplicity so entropy determines the direction.
Is it true because entropy is also a measure of disorder so because the highest disorder is more probable proves entropy is always increasing.

10:00
What is internally reversible path?

Is it isothermal, adiabatic, constant pressure, constant volumes, isentropic?

[ivanflebus]

Thanks alot, very helpful and clearly explained!

[allenkarahasan]

Such a dumb question but I cannot remember why does const pressure = const temp? thank you for your videos

[justarandomcatwithmoustache]

The way to spell "cyclic" makes me shiver...although the video is good

[bilalcicek]

Dear Teacher, I want to study rest of the chapters but I cannot do it. Can you make videos of the rest of the lessons?

[arshadansari-ezqe]

htas off sir for explaining a tough topic

[dremr]

6:45 explaining the effect delQ/t integral has....

[nicoleng]

noooo why dont you have chaps 9 to 12 T.T

[qjrvmob]

Is the cyclic integral of dQ/T entropy?
Apparently not because of the Clausius inequality being < 0 for irreversible.

Why this cyclic integral not delta s?
Thank u

Increase in entropy of an irreversible cycle is always > 0.

Could u please clarify, because the Clausius inequality is not intuitive at the least at first look.

[gooddeedsleadto]

Entropy generation makes the process irreversible?

Only extremely slow processes have no entropy generation and irreversible?

[bhaktikajale]

if entropy is always increasing, how is entropy neg for irreversible process? (in equation dQ/T<0)
