The Gibbs Paradox, Shannon Information Entropy, and Quantum Particle in a Box - Lecture 13

MIT OpenCourseWare via YouTube

Overview

Explore advanced thermodynamics concepts in this MIT lecture focusing on the Gibbs Paradox, Shannon Information Entropy, and quantum particle behavior in a box. Begin with a comprehensive review of mixture properties and isothermobaric mixing before delving into the Lennard-Jones potential and ideal Gibbs-Dalton behavior. Learn about semipermeable membranes and their applications, followed by a detailed resolution of the Gibbs Paradox. Examine information theory through Shannon entropy principles, then transition to quantum mechanics with a detailed model of a structureless particle in a box. Master the relationships between energy, entropy, and quantum probabilities while understanding the steepest entropy ascent evolution. Conclude with an analysis of the ideal gas equation of state for a single particle and an introduction to ideal solution behavior. Recommended viewing at 1.5x speed for optimal learning efficiency.
