Thermodynamics | Lecture- 4 | Chemistry Class 11, JEE, NEET, CUET.

📕Topics covered in this video:- 👉 Internal Energy (E/U) 👉 Characteristics of Internal Energy. 👉 Change in Internal Energy (∆U) (By doing work or by heat) 👉 Pressure - Volume Work ( P-V work for Irreversible Process) 👉 Mathematical Expression for 1st Law of Thermodynamics. --------------------------------------------------------------------------------- 👍Welcome back, students! In today’s session, we are diving deep into Chapter 5: Thermodynamics from the Class 11 Chemistry. Thermodynamics is a crucial pillar of physical chemistry that explains how energy moves and transforms in the universe. Whether you are preparing for your Class 11 School Exams, JEE, or NEET, this video covers everything from the basics of systems and surroundings to the complexities of Gibbs Free Energy. 📍 What You Will Learn: Basics: System, Surroundings, and Types of Systems (Open, Closed, Isolated). State Functions vs. Path Functions: Internal Energy (U), Enthalpy (H), and Work (w). Laws of Thermodynamics: Detailed explanation of the First, Second, and Third Laws. Exothermic vs. Endothermic: Understanding heat flow and enthalpy changes (∆ H). Entropy (S) and Spontaneity: Why do certain reactions happen on their own? Gibbs Free Energy (G): The ultimate predictor of chemical spontaneity.
