I speak for many people when I say I don't learn much from textbooks. My brain just doesn't work that way. These videos are worth their weight in gold! Just know that many of us wouldn't be making it without you! Thanks!

Thank you for your kinds words. I am really happy these videos help you out. Not everyone learns the same way, so while some students benefit greatly from textbooks, some might not, and that's perfectly fine. I made these videos as a supplementary tool in addition to lectures and textbooks. So I wish you the best, I hope all of these videos help you out and do your best :)

My suggestion topics for next videos: Maybe these are more towards Applied Thermodynamics 1. Reciprocating Air Compressors 2. Steam Power Cycle 3. Gas Turbine Power Cycle 4. Reciprocating Internal Combustion Engine 5. Refrigeration 6. Psychrometry

Thank you so much for your input, I appreciate it. I will add those to my list to do, but for now, this is the end of the thermodynamics videos. Most likely, the next set of videos will about electric circuits/ circuit analysis. I also need to create more shorts/videos about mathematic fundamentals since I get so many comments asking questions about those topics.

how would you know when to assume constant or varible spacific heat?

@QuestionSolutions 4 ай бұрын

So that depends on the givens. Did you watch the video before this about entropy and ideal gases? I talk about both methods in that video. Please take a look at that one first, thanks!

Why do you do these videos?

@QuestionSolutions 4 ай бұрын

Few reasons. I wish I had something similar when I was studying engineering, with animations and more problems solved step by step. These seem to help a lot of students now, and it's supplementary to course work. Also, I really enjoy reading nice comments, especially when these videos help students out. I guess another way to answer your question is, why not? :)
