NEET Thermodynamics is small in syllabus but predictable. Most questions involve the first law (Q = ΔU + W), efficiency of Carnot engines, isothermal/adiabatic process equations, and the ideal gas law. Heat capacity ratios (γ = Cp/Cv) and degrees of freedom for monoatomic, diatomic, and polyatomic gases come up most years. The chapter is short enough that you can fully cover it in 4–5 days of focused prep.
NCERT chapters to cover
- 📘Class 11 Ch 11: Thermal Properties of Matter
- 📘Class 11 Ch 12: Thermodynamics
- 📘Class 11 Ch 13: Kinetic Theory
Exam tips
- 1Always note whether a process is isothermal, adiabatic, isobaric, or isochoric — most thermodynamics mistakes come from misidentifying the process.
- 2Carnot efficiency η = 1 − T_cold/T_hot is one of the most reliable formulas — almost guaranteed 1 question.
- 3Don't forget kinetic theory: equipartition of energy and degrees of freedom show up reliably.
