Lecture 99: Entropy, Clausius Inequality, and Thermodynamic Irreversibility | JEE Physics Class 11

by

Welcome to Lecture 99 of our comprehensive JEE Physics Master Series. In this lecture, we rigorously formalize Entropy and the Clausius Inequality, provide 4 graded solved examples, and deliver a 10-question practice worksheet (DPP) complete with answer key and step-by-step solutions.

Lecture 98: Carnot Cycle, Efficiency Derivation, and Reversed Carnot Engine | JEE Physics Class 11

by

Welcome to Lecture 98 of our comprehensive JEE Physics Master Series. In this lecture, we derive the Carnot efficiency from first principles, dissect the four reversible stages on P-V diagrams, analyze reversed Carnot engines (refrigerators & heat pumps), and solve high-yield JEE Advanced problems.
