In this video, you'll learn a more accurate description of entropy and understand how it relates to the concept of spontaneity. This video is part of the Governing Rules video series. A small number of rules describe the physical and chemical interactions that are possible in our universe. Hi. My name is John Lienhard and I am a professor in the Department of Mechanical Engineering at MIT. Today, I'm going to talk to you about entropy, a fascinating, but often confusing topic. In order to understand the topic of this video, you should be familiar with the idea that energy is quantized and the thermodynamic ...
