this vid and the one about PV diagrams and internal energy (about 4h long) summed up my entire thermodynamics in physics degree im so glad this vid exists

[@ahmadsleiman37]

I'm confused, I am given to study thermodynamics as in chemistry and everyone is saying its physics tf?

[@2averageguysgaming339]

@@ahmadsleiman37 Probably thinking of thermochemistry. If not, chemistry and physics do tend to have many overlaps in some areas so im not too surprised.

thank you so much! with your videos I'm learning more than I have ever learned at school! i started to understand physics normally, all with the help of your explanation.

Came across this vid then realized, Im paying my tuition fee in university for nothing.

You are not the only one out there......

[@CStark20]

The worst part... Is that I'm paying tuition in the US...

[@theyammi437]

God, my professor is so bad at lecturing.

[@JamesVestal-dz5qm]

Every year tuition increases and student outcomes decrease.

If you can learn on your own with KZbin. Then use college to meet people who can further a potential career after graduation.

[@SpontaneousCube]

Absolute king, all your videos are so helpful! The lecture notes on thermodynamics were hard to understand but you just simplified the whole process thanks! Keep doing what you're doing

This topic is very hard to me.. How u can help me...thermodynamic.. Come on In my whatsapp through this number [phone]

[@jackietse6495]

I watched so many videos and looked up explanations on google to try to understand these topics but less than a couple minutes after watching your videos, everything just makes sense. You really break things down so simply. Thank you!! D:

[@paulinjosepha2336]

Many Thanks for your time and this helpful video. My roommates said Thermodynamics is hard. however, in 1h :18 min and 25 second. I understand the HARD THERMODYNAMICS. May my almighty God bless you and give more energy to pu on the Helpful videos like this one . Again, thank you so every much for time and Bless you hear.

Yo thanks for the lesson, the way you explain is way more better than my teacher at my school, once again thank you.

[@Soor101]

First of all, WOW!! So helpful! I'm a little confused about the ideal gas problem - So in my ChemE thermo class we talk about the entropy change of an ideal gas as delta S = integral of Cp*dT/T - ln(P/P0)*R. Now this would equal zero for a reversible process, but nowhere in the problem does this say that it is reversible and the only ispentropic processes are reversible and adiabatic. I'm not sure what to think because your reasoning makes sense here but I'm sure if you have an irreversible adiabatic process there's an entropy change, as all irreversible processes have entropy changes. This is quite a thinker...

[@Rei-fm9yw]

When work is done on the system, to compress the gas, the work is positive because it is added into the system.

[@carultch]

There are different sign conventions. The heat engine sign convention assigns work as positive when the system provides the work, and heat as positive when it is added to the system.
