TED-ED: What is entropy? - Jeff Phillips

The video explains the concept of entropy, a key idea in chemistry and physics, often misunderstood as disorder. It introduces entropy through probability and microstates, showing how energy distribution affects entropy levels. The video discusses dynamic systems where energy moves, explaining why spontaneous processes occur. It highlights that higher entropy states are statistically more likely, explaining real-world phenomena like ice melting and cream mixing. The video concludes that entropy is a measure of energy spread, not disorder, and is crucial for understanding physical processes.
