Chemical Engineering Thermodynamics | State Functions, Energy & Equilibrium | lec - 2 | 3rd Semester

📚 Chemical Engineering Thermodynamics | Thermodynamic Systems & Properties | Lecture - 2 | 3rd Semester

🔥 इस लेक्चर में Chemical Engineering Thermodynamics के Unit-1 की शुरुआत की गई है। इसमें Thermodynamics का परिचय, Thermodynamic System की परिभाषा, Types of Systems (Open System, Closed System, Isolated System) तथा Thermodynamic Properties (Intensive & Extensive Properties) को सरल भाषा में विस्तार से समझाया गया है।

🎯 यह लेक्चर BTEUP, Polytechnic तथा Chemical Engineering 3rd Semester के छात्रों के लिए बहुत महत्वपूर्ण है। परीक्षा की तैयारी, Viva, Class Notes तथा Concept Building के लिए यह वीडियो बेहद उपयोगी रहेगा।
