What is Temperature?

Показать описание

"What is temperature?" is a surprisingly tricky question. In this video we approach it in three levels of difficulty. Going from our every day notion of temperature all the way to its fundamental roots in statistical thermodynamics.

This video, along with your entropy one, is the best explanation of Entropy and Temperature I've seen. I've never considered becoming a Patreon before, but I know that this sort of content would have changed how I thought about and understood stat mech/thermodynamics in a fundamental way when carrying out my undergrad (and even my comp. chem. PhD) and the world needs more of it.

Mark my words, this is the best video on temperature and even about entropy. All I have seen in textbooks about entropy is " Rate of Disorder " . I was like mostly C'mon.😂

finally, some youtube channel that does science and is not 1.5x speed. Thank you so much for this!

Incredible video, hope to see more. Fantastic explanation and visual representations!

Great video! Clearly explained and amazing visualizations as always. Nice that you are back!

Nice explaination. Very glad that you are back. Keep it up. We want to see more videos.

This is my first time hearing Gordon Freeman speak. Thank you for the explanation, Mr. Freeman

So many things I'd like to share, but I'm happy to see that much of what I had to say has already been said in other comments. However that may be, I'll still chip in and thank you, from the bottom of my heart, for making such an instructive and frighteningly clear video on this subject. I'm a physics PhD student, and I have a class to prepare for tomorrow precisely on entropy and temperature. They have absolutely no idea what's coming for them now that I have seen this video. Peace man, wish you long-living, and much earned success.

Thank you because you open up a world to me, these are the kind of videos I look for on youtube and they really make me understand the concepts I study!
The visual approach to these topics is the best!
Keep it up!

Sehr schöne und anschauliche Erklärung!

Hey @MarbleScience !
Again, a tremendeous video! Thank you and looking forward to the next!

Great video again! I really like the visualisations and the intuitive connection with statistical thermodynamics!

Thank you so much! I’ve been trying to wrap my head around this for years now, watching multiple videos and my teacher explaining it couldn’t help.

It’s so easy to understand and now I know what causes heat damage. I knew temperature had something to do with atoms moving but not how it caused damage/brain recognition.

great video! I kind of believe that temperature represents how chaotic a system is. just like in your video, low temperature means that the particles have an untapped potential: their movement is confined due to many physical interactions. then you heat up the system and they start depleting their potential and can fill up a wider space due to random motion. what we feel as "heat" is exactly this unordered motion - if it were the average kinetic energy of the particles, then you would be able to just heat up anything by simply blowing air at it 😃
