    Once again thank you for keeping on teaching us. You are one of the most prestigious teachers on this youtube platform. Sorry for being demanding but can you do advanced chapters of thermodynamics 2 as well?

      Thank you very much! Right now, my plan is to cover the chapters needed for a 1st or 2nd year course. Usually, there are some overlap with those and advanced chapters. My goal is to create a few playlists of all the fundamental courses so students can grasp those concepts and hopefully make their transition to more advanced courses easier. So I might not go really deep into the advanced topics because I will switch to another subject and cover the basics of that. But I will do my best so let's see where that takes us :)

    Hi again I have another question here about 3:58 .Why Wnet equals to _Wout - Win_ but not _Win - Wout_ ? I am grateful ,you always help with your viewers' questions 🙂

    • @QuestionSolutions
      @QuestionSolutions  11 месяцев назад +2

      So in a heat engine, our goal is to get work output. But a heat engine requires energy for it to work. So if you want to figure out how much net work output was "created" by the heat engine, then you have to subtract the amount of work that was put into the system from the amount of work that was produced by the system.

      @@QuestionSolutions Oh I see.Lastly why we add _out_ in the subscript for *Wnet* and it becomes *Wnet,out*?

      Out, as in output. So what is the total net output, or in simple terms, what did we gain from this heat engine. @@yigitcan824

      Right now, I am leaning towards electric circuit analysis. I don't know when I can start that yet, but I will see. I also need to create some shorter videos covering how to solve simultaneous equations, when to use sine or cosine, etc., since I get a ton of questions on those fundamental topics.

    @ 7:30, don't you mean "work per second" instead of "power per second"...? Just pointing out. Other than that, thanks for the great video!

    • @QuestionSolutions
      @QuestionSolutions  Год назад

      No, I mean power. So power is the rate of energy transferred during a specific time, with the units W for watts. 1 Watt = 1 J/s. Hope that helps 👍
