Entropy Explained - Why Heat Only Flows From Hot to Cold

The video explains entropy through intuitive examples, focusing on the second law of thermodynamics. It introduces entropy as a measure of multiplicity, using Boltzmann's constant. The video clarifies misconceptions about entropy being disorder and uses examples like gas molecules and coin flips to illustrate microstates and macrostates. It highlights the probabilistic nature of entropy, showing that systems tend to move towards states with higher multiplicity. A simulation demonstrates how entropy leads to even distribution of energy, explaining why heat flows from hot to cold.
