Reversing Entropy with Maxwell's Demon
The second law of thermodynamics - the law that entropy must, on average, increase - has been interpreted as the inevitability of the decay of structure. This is .... misleading. Structure can develop in one region even as the entropy...

The Misunderstood Nature of Entropy
Entropy is surely one of the most intriguing and misunderstood concepts in all of physics. The entropy of the universe must always increase - so says the second law of thermodynamics. It's a law that seems emergent from deeper laws - ...

TED-ED: What is entropy? - Jeff Phillips
There's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's...

Entropy is not what you think!
We explore the fundamental nature of entropy and its deep link to information. If you were taught that entropy measured disorder, you are in for a treat!

The Third Law of Thermodynamics: Absolute Zero
Brr, it's so cold today! Could it get any colder? Is there a coldest possible temperature? Yes, there is! That seems strange, but now we know that temperature is just a measure of kinetic energy, so zero kinetic energy must mean zero...

The Second Law of Thermodynamics: Heat Flow, Entropy, and Microstates
What the heck is entropy?! You've heard a dozen different explanations. Disorder, microstates, Carnot engines... so many different wordings and interpretations! Really, they are all related, so let's go through a few different...

Entropy Explained - Why Heat Only Flows From Hot to Cold
Entropy explained with simulations. Intuitively understand entropy. Why Heat only flows one direction. Physics lecture with simulations of the system. The reason is because of statistics and more specifically multiplicity. We will...

Macrostates and Microstates, Thermodynamics, Physics
Sal introduces Macrostates and Microstates in this chemistry video. He shows students that pressure, temperature, and volume are considered to be in the Macrostates category. However, kinetic energy, force, and velocity are considered to...
