When Does a Gas Reject Heat? | P-V Diagram Trick 🔥| JEE Physics Understand one of the most important concepts of Thermodynamics and P-V Diagrams for JEE Main, JEE Advanced, NEET, and Class 11 Physics. In this short lecture, MB Sir (Mohit Bhargava - AcaDXL) explains the exact condition when a gas starts rejecting heat in a P-V process. Learn the relationship between pressure, volume, work done, heat transfer, and thermodynamic processes with simple graphical analysis. This concept is frequently asked in competitive exams and helps build strong fundamentals in Heat & Thermodynamics. Watch the complete short for quick conceptual clarity and exam-oriented problem-solving techniques.
