Im from Korea and being able to see English subtitles is really helpful. I can fully concentrate on the lecture. Thank you very much and u r helping lots of people than you think!
Professor Miller and all the colaborators that made this video possible. Thank you so much for your help!! I am an Engineer from Chile and thanks to these videos and classes, I was able to got recognized my credentials in Canada. I did passed my 2 exams in the first attempt ( Thermodynamics and Heat Transfer) in order to get my recognition as an Mec Eng. Still, there is lots of road ahead, but being able to work in my field broad is one dream achieved. Keep it going guys please, hopefully there is more projects like this. You are helping a lot. Thank you so much again!!! 🎉🎉🎉🎉
Thank you for the lecture! This is what I found online. A thermodynamic process taking place at constant volume is known as the isochoric process. It is also sometimes called as an isometric process or constant-volume process. The term isochoric has been derived from the Greek words “iso” meaning “constant” or “equal” and “choric” meaning “space” or “volume.”
When the ancient Romans referred to weight, they used the term libra pondo. Libra meant "weight" or "balance scales," and pondo meant "pound." They eventually shortened the phrase to just libra, which they abbreviated “lb."
A small mistake was made at the very end but it has been corrected at the start of the next lecture. It was supposed to be "Molar Specific Volume = Molar Mass x Specific Volume " but the professor wrote " Specific Volume = Molar Mass x Molar Specific Volume ".
Isn't it technically incorrect to say pressure of the cup of water doesn't change? The pressure at the bottom of that system of water is slightly higher than the water at the top. I guess it's just negligible.

Even native English speakers often like to see subtitles. :)

great lecture sereies
After 22 years of taking this course, i refresh it with you, professor

Hooray! We're glad this channel helped.
This is my 3rd time taking this course and this is the first time I am understanding it. Thank you from Ottawa, Canada! God Bless!
Fiiiiiinally. :)
Started watching this series last month. I'll come back here once I've graduated.
best of luck
Thank you for the lecture!

Have this guy teach the ChemE department!!!
i am from egy and i had watched your vid
so i think your the best thermodynamics prof ever
Thanks a lot, that was precious 👍

I love you
Cal poly pomona
:D
I will watch all your videos In Shaa Allah
Just subscribed the channel!! I'm thrilled to learn thermodynamics!!! Thanks.......
We have a lot of thermo... and fluids... and heat transfer... and other stuff. :D
I like it so much and it's very good.
Thanks a lot!
I need this
Awesome lecture
What are examples of independent properties I thermodynamics? And independent intensive properties??
can you please share this lecture's homework problems. thank you
thank you very much
Is there a list of homework problems used in this course? I couldn't see it on the syllabus.
Sorry, we won't have a list available.
What a wholesome prof
He's nice in real life too.
Where can I find problems to solve
could you tell which textbook has been used, please?
Cengel & Boles, "Thermodynamics, An Engineering Approach" (8th edition). The 9th edition is out now.
is this course a prerequisite for heat transfer?
Yes, this is a pre-req for heat transfer in the ME Dept at Cal Poly Pomona.
Isn't it technically incorrect to say pressure of the cup of water doesn't change? The pressure at the bottom of that system of water is slightly higher than the water at the top. I guess it's just negligible.
yep, it's quite small difference, so we can neglect it
Very nice helpful lectures!
Thanks!
Let's call it the Imperial System of units. The acronym is IS, and it could also be taken for the International System.
Please can you tell me Which Thermodynamics book is being followed
Thank you
Cengel & Boles, "Thermodynamics, An Engineering Approach" (8th edition).
I have 7th edition
i believe Things are same almost except problems a little
Thanks
The content is pretty much identical, but many problems have changed from the 7th to 8th editions.

Thanks a lot sir you are saving our career and life ❤️❤️❤️
Who knew that thermo could save lives...
can i get the paper he wrote,please?
Sorry, the papers were not saved.
