It's my second time around taking thermo, luckily this time I have the guy that got me through statics, solids, and dynamics.
me too. I hope we are approved this semester
Hope all went well! I had to repeat dynamics. Don't give up.
I've been watching the playlist of online Statics lessons and learning a lot from you Dr. Jeff. Thank you! Also, I've just started to watch Thermodynamics classes and as usual, while listening to the lesson calmly, 0:22 this special shout out made my day! I definitely didn't see that one coming. Loves from Turkey.
00:20 As a Turkish American engineer living in US, I love your classes Dr. Hanson! Thank you for all the videos.
Joining from turkey as a engineering student and I love this dude’s explanation, and when he gave out thanks to turkey joining I was flabbergasted 😂😂😂
Thank you for making these! You're such a clear and direct professor. I love it and appreciate it! I am in thermodynamics now so I'm looking forward to the rest of your thermo videos, hopefully you can do some of the later topics such as pumps, heat exchangers, etc.
Just started Intro to Thermo. This all was a great refresher. Thanks for posting this!
I’m applying for thermo classes this semester so this comes really handy, thank you :)
Thank you! I have to learn the basics of Thermodynamics in a short period of time and this is really helpful!
Greeting from the Netherlands
What a blessing... I am taking dynamics and thermo this semester and it's like I have 2 professors and double the examples
Thank you for uploading so frequently!
I have already taken thermo and this guy is making everything way easier to learn compared to my professors. A very good refresher!
Watching from Michigan Tech, Morse recommended you in static’s, and now you’re making videos in therm! Perfect timing
Please tell the Morses hi from me!
Watching from West Virginia University! Really happy I discovered this channel and your videos.
I’m a DePaul physics student who didn’t have the opportunity to take this class, but wants to break into engineering via space companies. This class and video lecture series are a godsend. Thank you good sir for broadening my knowledge
The hamburger example was fantastic, actually! Great video, thanks, Jeff!
Wonderful Thermo lessons!! really taking the time to explain the problems along with a good sense of humor :))
Hi Dr Jeff, I'm an aerospace engineering student from the UK and find your content really great, thanks for doing what you do. : )
Thank you so much I never got thermo but I get it now. You’re a great teacher!
I appreciate all the person like you who love to share their knowledge. Im from the Philippines. Pls keep eduacting us. 🙏💓
The food example explained it to me perfectly omg!!!!
These are awesome refreshers .
Hey dr jeff, I just got out of my thermo finals, I am kind of sad you didn't make this course earlier but atleast now I know the future mechanical engineers will have you for this subject aswell.
If I may offer some student feedback, property tables were a struggle for me and many others, there weren't any youtube videos on them, so if you can you should make a whole lesson just about them
you prolly dont give a shit but does anybody know a way to log back into an instagram account??
I somehow forgot the account password. I love any assistance you can offer me.
Thank you! I was struggling to understand enthalpy. This was very helpful for the thermochemistry section of my chemistry class!
Thanks you so much, I'm taking this class in summer and it's really helping me out. Please make more
0:23 hello Mr. Jeff, thanks for lessons. greetings from Turkey 🇹🇷 (:
Great way to visualize internal energy.
I really need this concept.. thanks sir.. i have hard time in understanding this topic..
Dear Dr Jeff, I am retired now but did "A" level Chemistry here in UK 50 years ago. Never really got Entropy until now. Better late than never. ta! R
I finished Thermo with a 98%. Had no idea what I was doing. Do I know what any of these things mean? Nope! It's a variable with some units... I mathed my way through it: variables and units - who cares. This is a great video. A lot of what I was doing makes sense now. Thanks!
Hello Dr. Jeff,
I am not from Turkey but if I was I would have loved the shoutout. Very cool!
Loves from Canada
ahhh you're such a fun teacher! Def subscribing!
absolutely fantastic teacher, my current teacher is a nightmare, nice to be able to understand it in clear, and plain simple English!
Thank you! keep on rockin
Thank you so much!
You have a fun way of teaching 👍
Thank you Dr. Jeff
elo bayaw, gudlak!!
I totally saw someone with this shirt that you're wearing at Walt Disney World this weekend and I was tempted to go up to him and ask him if he knew you.
thank you sir. greetings from Turkey.
Taking Thermo over the summer to graduate in two years. Thank god for these vids 😂
Excellent lecture
This guy's videos derserve waayyy more likes
You are the best
Thank you ❤
thank you, infinite respect from Kurdistan
Love you from Turkey
Great video professor. I have a question. Is heat in the form of convection, the flow of enthalpy through a control volume or is it just the flow of internal energy?
Sir, would you please do fluid mechanics and dynamics next? Loving the thermo course so far!
Agramer he already has a dynamics playlist!
Starts talking about internal energy at 10:45
hey Dr. Jeff, when should we expect a lecture on the second law of thermodynamics
i hope you will consider next the quality (x) concept
Sir plz continue dynamics
this semester's gon be a disaster, but here you are...salamuch
I'm not sure If you noticed but lesson 3 and 4 audio volume is waaaaaaaaaaay smaller than the Lesson 7, 2, 1 you posted recently. We can hear what you are saying at max volume using computer, but something to look into? (maybe it's just my computer but) Always appreciating what you make for us Mr. Hanson. Be the guiding light of us engineering students tysm
Thanks for the info. I may have to redo. Thanks!
Hi Dr. Hanson, at 14:35, you said entropy will be low at equilibrium state, however Wikipedia said it would be at max (highest) entropy
The equilibrium represents State of non directionality while 2nd law of thermodynamics represents directionality of maximum entropy. So at equilibrium entropy of surroundings will be maximum . But since we deal only with system so we move to a property namely Gibbs free energy to determine if system is in phase/chemical equilibrium.
The equilibrium represents State of non-directionality (dynamically static state); while 2nd law of thermodynamics represents directionality towards maximum entropy. So, at equilibrium, entropy of surroundings will be maximum . But, since we deal only with the system so we move to a property namely Gibbs free energy to determine if system is in phase/chemical equilibrium.
wow
Higher the enthalpy or enthalpy change, higher the work produced by the system?
Lower the entropy change higher the work produces by the system?

I'm almost finished with my apprenticeship as a Diesel mechanic. But i am interested in Aerospace engineering. I read somewhere the I'll need a lot of thing done before i do amy Aerospace courses. But i'll get there one day right?
If you work towards your goal…you will get there! Who’s going yo stop you?
11:44
It's like Steven Spielberg, but from Texas and teaches engineering.
jeff why did you started to thermodynamics before finishing the dynamics
yeeey Turkeeey yaeeeeooooaaeeuuyyy
I trusted you :(
.
so I will not pass final exam
How did it go? Did you pass?
this semester's gon be a disaster, but here you are...salamuch
