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! Chapters: 00:00 Intro 00:10 Macro- and Microstates 02:06 Entropy is Not a Property...

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...

Khan Academy: Chemistry: Macrostates and Microstates
A video lecture exploring the difference between macrostates, microstates, and thermodynamic equilibrium. Understand how macrostates is best defined when the system is in thermal equilibrium and describes pressure, temperature, and...

Khan Academy: Chemistry: More on Entropy
A video lecture describing how entropy is a macrostate variable that also describes the number of states a system can take on. The video explains some misconceptions about previous given analogies to describe entropy. [9:30]
