Thermodynamics — NEET/JEE Questions, Notes & Weightage
Class 11 Heat & Thermodynamics NEET weightage: High 2,041 questions
Covers the first law of thermodynamics, thermodynamic processes (isothermal, adiabatic, isochoric, isobaric), and heat engines/Carnot efficiency. P-V diagram interpretation and work-done-in-a-process numericals are tested almost every year.

What is the most important numerical skill here?
Calculating work done, heat absorbed, or change in internal energy for a specific process (especially isothermal and adiabatic) from a P-V diagram is the chapter's core, recurring skill.
Is Carnot engine efficiency tested directly?
Yes — calculating the efficiency of a Carnot engine from given source/sink temperatures is a standard, frequently repeated numerical.
