  • Second Law Of Thermodynamics - Unifyphysics


    This course explores the Second Law of Thermodynamics, which governs the direction of natural processes and introduces the concept of entropy (S)—a measure of disorder or energy dispersal. You will learn why some processes are spontaneous (e.g., ice melting) while others are not (e.g., heat flowing from cold to hot). Key topics include Carnot cycles, Gibbs free energy (G), and thermodynamic efficiency, with applications to engines, refrigerators, and biological systems.
