    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.

      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.

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

    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 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.

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

    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

    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

    • @tajammulkha_n6791
      @tajammulkha_n6791 2 ปีที่แล้ว

      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.

    • @tajammulkha_n6791
      @tajammulkha_n6791 2 ปีที่แล้ว

      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.

    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!

    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?

  • @hsl0827
    @hsl0827 5 ปีที่แล้ว +1

    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?
