Thermodynamics gave 10 of the 387 NEET Physics questions asked between 2020 and 2026 (Re-NEET 2026 included). That is 2.6% of the subject and the #19 chapter out of 30 by weightage, about 1.3 questions per paper. It peaked at 2 in NEET 2020.
Of the 10 questions tagged for difficulty, 60% were easy, 20% medium and 20% hard, so this is a chapter where NCERT-level preparation pays off directly.
It has been asked more often lately: 1.7 questions per paper across 2025, 2026 and Re-NEET 2026, against 1 per paper in 2020–2022.

What the latest papers asked
Topics from NEET 2026 and Re-NEET 2026:
- Internal Energy (Internal Energy and its Change)
- Thermodynamic Processes (Cyclic Process)
Where the hard questions came from
- Internal Energy (Internal Energy and its Change): 1 hard of 2
- Thermodynamic Processes (Adiabatic Process): 1 hard of 2
How to use this data
- No single topic dominates here. The 7 topics are spread widely, with 4 asked only once, so cover the whole NCERT chapter rather than a short list.
- 60% of tagged questions were easy, so NCERT lines, definitions and standard examples are worth locking in first.
- 20% were hard. After the basics, practise multi-step and application questions from the hard-tagged topics.
- Re-solve the 2 topics from NEET 2026 and Re-NEET 2026, since they show the current style of questions.
- Then attempt the chapter's past questions under a timer and note which topics cost you marks.
