In this complete First Law of Thermodynamics ONESHOT, our expert Chemistry faculty explains one of the most important and scoring chapters of Class 11 SEM 2 Chemistry, specially designed for HS 2026 students of WBCHSE.

This lecture is part of our Dhurandar Series, created for students who want maximum concept clarity + exam-oriented preparation in minimum time.

🔥 What you’ll learn in this video (Thermodynamics Focus):

✔ First Law of Thermodynamics full chapter – Class 11 SEM 2 Chemistry
✔ Concept of system, surroundings & universe
✔ Internal energy (ΔU) and its significance
✔ Heat (q) and work (w) – chemistry convention
✔ Mathematical form of First Law of Thermodynamics
✔ Isothermal, adiabatic, cyclic & free expansion processes
✔ Work done in different thermodynamic processes
✔ Sign conventions (very important for numericals)
✔ Numerical problem-solving (board & exam oriented)
✔ Common mistakes students make in thermodynamics
✔ Important definitions, formulas & keywords for exams

🎯 This Chemistry ONESHOT is ideal for:

📌 HS 2026 Class 11 SEM 2 Chemistry students
📌 Students who find Thermodynamics confusing or numerical-heavy
📌 Students preparing for Class 12 Physical Chemistry base
📌 Last-moment SEM / annual exam revision
📌 Beginners who want crystal-clear concepts
