    so glad to see you posting again, you really helped me understand relative motion analysis and im taking thermo-dynamics next semester so im sure ill be watching a lot more videos. Thank you so much for the help!

      I am really glad to hear the videos helped you understand relative motion. Hopefully, the thermodynamics videos will help you out too. I've been really busy these days so I haven't been able to finish the next video, but hopefully soon, I can upload it :)

    you are amazing and I like your videos and the way you explain, you're the best teacher I have ever seen I'm appreciate you.
    if it possible I would like net time heat transfer, this subject I confused because it has a lot of proves and concepts those apply the example and I'm sure if do this it will be easier I hope you do soon. thank you again

      A location, a place, a system, that has a relatively higher temperature than a location, place, or a system that has a lower temperature. So it could be a room, the space inside a fridge, etc.

      Thank you for your suggestion! So it's on my to-do list but I really don't know when I would get around to it. I think there might be a lot of videos on the subject on UA-cam as well. So hopefully, they will be helpful to you :)

    in 7:44 how do i know if the given is Qh or Ql its confusing

    • @QuestionSolutions
      @QuestionSolutions  11 місяців тому

      So whenever heat is rejected ("thrown away into the environment") into the environment, it's QH, and whenever heat is taken "away" from some space, like your freezer, that amount of heat is QL.
