Thermo: Lesson 3 - What is Entropy, Enthalpy, Internal Energy 

00:20 As a Turkish American engineer living in US, I love your classes Dr. Hanson! Thank you for all the videos.

It's my second time around taking thermo, luckily this time I have the guy that got me through statics, solids, and dynamics.

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.

Watching from Michigan Tech, Morse recommended you in static’s, and now you’re making videos in therm! Perfect timing

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.

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

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

I’m applying for thermo classes this semester so this comes really handy, thank you :)

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 😂😂😂

ı am watching you from Turkey Izmir . First watched strenght of materials and now ı am keep going with thermo.

I have already taken thermo and this guy is making everything way easier to learn compared to my professors. A very good refresher!

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! 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

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

0:23 hello Mr. Jeff, thanks for lessons. greetings from Turkey 🇹🇷 (:

I appreciate all the person like you who love to share their knowledge. Im from the Philippines. Pls keep eduacting us. 🙏💓

Just started Intro to Thermo. This all was a great refresher. Thanks for posting this!

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!

Thank you Dr. Jeff

Thank you so much I never got thermo but I get it now. You’re a great teacher!

The hamburger example was fantastic, actually! Great video, thanks, Jeff!

Hello Dr. Jeff, I am not from Turkey but if I was I would have loved the shoutout. Very cool! Loves from Canada

Watching from West Virginia University! Really happy I discovered this channel and your videos.

Wonderful Thermo lessons!! really taking the time to explain the problems along with a good sense of humor :))

I really need this concept.. thanks sir.. i have hard time in understanding this topic..

Thank you for uploading so frequently!

Thank you! I was struggling to understand enthalpy. This was very helpful for the thermochemistry section of my chemistry class!

absolutely fantastic teacher, my current teacher is a nightmare, nice to be able to understand it in clear, and plain simple English!

The food example explained it to me perfectly omg!!!!

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.

Great way to visualize internal energy.

Thanks you so much, I'm taking this class in summer and it's really helping me out. Please make more

thank you sir. greetings from Turkey.

Taking Thermo over the summer to graduate in two years. Thank god for these vids 😂

ahhh you're such a fun teacher! Def subscribing!

You have a fun way of teaching 👍

This guy's videos derserve waayyy more likes

These are awesome refreshers .

thank you, infinite respect from Kurdistan

Sir, would you please do fluid mechanics and dynamics next? Loving the thermo course so far!

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

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

Higher the enthalpy or enthalpy change, higher the work produced by the system? Lower the entropy change higher the work produces by the system?

this semester's gon be a disaster, but here you are...salamuch

Starts talking about internal energy at 10:45

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?

You are the best

Sir plz continue dynamics

Thank you ❤

Love you from Turkey

Excellent lecture

Thank you! keep on rockin

Thank you so much!

i hope you will consider next the quality (x) concept

hey Dr. Jeff, when should we expect a lecture on the second law of thermodynamics

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?

It's like Steven Spielberg, but from Texas and teaches engineering.

Dr. Jeff 9K = 5R

jeff why did you started to thermodynamics before finishing the dynamics

11:44

wow

11:30 😂

yeeey Turkeeey yaeeeeooooaaeeuuyyy

I trusted you :(

.

so I will not pass final exam

this semester's gon be a disaster, but here you are...salamuch
