Thermodynamics contributed 10 of the 387 NEET Physics questions between 2020 and 2026 (Re-NEET 2026 included). That is 2.6% of the subject and makes it the #19 chapter out of 30 by weightage — roughly 1.3 questions per paper, peaking at 2 in NEET 2020.
Of the 10 questions tagged for difficulty, 60% were easy, 20% medium and 20% hard — a chapter where NCERT-level preparation pays off directly.
It has been asked more often lately: 1.7 questions per paper across NEET 2025, NEET 2026 and Re-NEET 2026, against 1 in 2020–2022.
The single most-tested topic is Internal Energy (Internal Energy and its Change) — 2 questions across 2 papers.
7 topics tagged under Thermodynamics. Numbers show how many questions each topic had in each paper; E / M / H are the easy, medium and hard counts.
