I absolutley love your videos. It's always great to get another perspective on these topics and it has helped me get a better understanding of the topics. It is very refreshing to see the passion you express towards teaching. Thank you so much for the great videos and please keep up the great work!
Hi, Mr.Doner! I am loving your videos to study for the IB exams. I was telling my class about you and I just found out that you were a teacher at my school (Chapel School SP) !!!!! And that you taught my physics teacher, Mr. Delia !!!!! Very exciting news! Thank you for the videos , I am a fan!!!
Sir, You're doing a real good job! Please keep up the good work. I am really amazed that you've such low subsrcibers taking into consideration the quality of your videos. Please focus on some advertising if possible and if you're not doing this for money and just to help students. You aren't less than a Faithful Good Teacher. I too, know how much effort and practice it takes to be proficient with your videos on TH-cam or a website. Thank You Again. Aruj.
+Aruj Budhraja It isn't a matter of being humble. I know the videos are generally of high quality. Advertising revenue for a site of my size is not significant. I often use other people's material in my videos and I could not do this if I monetize. So for instance in the Entropy video, there is advertising for the clip that I borrowed for the music video, but the revenue would go to the people that made the music video. What do I get out of making the videos? 1) They make my day to day teaching far more enjoyable and less stressful. 2) I feel appreciated when I receive the many sincere thank you's from viewers. 3) I enjoy making the videos, and it has become a hobby. 4) It opens numerous opportunities for me.
Chris Doner you could most definitely use others people's material if your videos were monetised. Monetisation doesn't affect fair use. So I'd recommend you look into that
I would just like to thank you for a minute here, your videos have helped me tremendously and I cannot thank you enough for this! Physics HL has never come to me as clearly!
Hi, an amazing video. I just have one question. At 12:29 you state that the potential energy of the hotter body decreases, but how so? Does the potential energy not increase as there are lesser vibrations as temperature decreases and so there is more attraction between particles? eg when water is frozen it turns to a solid which has more PE and lesser KE. So, does PE (bonding) increase as particles are further apart or does it decrease? Thank you.
Could you kindly elaborate more on the definition of potential energy? Isn't potential energy the energy stored in a particle? How does bonding come in....?
Potential energy refers to how much energy something has by virtue of its position in a field. If a mass is high in the gravitational field of the Earth, it can fall along way, and has a lot of potential energy.
Hello Sir! The answer for the question "For two objects to be in thermal equilibrium they must ... be at the same temperature" would be completely acceptable if you didn't explain so well about the potential and kinetic energy. Namely, we know that the temp. is the measure of the avg. kinetic energy, so it means that for objects that have the same temp. it must be that they have the same EK. However, what about potential energy? What if that one is different (different bonding for example). Why don't we take in consideration also that when talking about equilibrium? Thank you!
+Rados Veselinovic Heat only flows when there is a difference in temperature, and temperature is proportional to the average KE. We are not talking about flow of molecules, just energy, so the bonding had nothing to do with whether heat flows. Different bonding can change how effectively heat can flow between two substances but not whether it can flow. This effectiveness is not a simple relationship like the proportionality between rate of heat flow and temperature difference.

That was the clearest explanation of the potential energy between particles I have seen; thank you!
Glad it was helpful!

Great to hear that someone from Chapel is watching my videos. I have many great memories of Brazil. Good luck on your exams.

More helpful than my physics teacher🙏🙏🙏🙏

Great to hear!
Thank you so much for breaking this down for us. You’re amazing!
thank you so much for these videos !! you’ve helped me so much and i feel a a lot more confident about the content, v grateful for this channel :))
Great to hear. Spread the word.
Thank you so much as usual ! Excellent videos
Thank you, this is what is making me pass my IB
Thank you. Please spread the word about the channel, become a subscriber or a member.
thank you sir!! i have finals coming up soon and your videos have been really great help :)
Hey chris i would like to thank my parents from here for they've let me play with sparklers in my youth, thanks
Thank you so much!!

Never mind, you answer this at the end. Was confused while taking notes. Thanks again.
SO HELPFUL..........So HELPFUL
Nice to hear!
Thank you chris D !!!!!
thank u for the videos!
thank you for this, good sir
keep it up boss!
Will do!
Thank you!
You're welcome!

Is it still up to date?
Yup.
