NEET 2022 Physics Thermodynamics Questions
Use this page to connect the official 2022 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
state variables, heat, work, thermodynamic processes and heat engines.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
A rigid container receives 450 J of heat while its volume remains constant. Neglecting all work modes other than pressure-volume work, what is ΔU?
- A. +450 J
- B. 0 J
- C. +225 J
- D. −450 J
Example 3 · difficulty 2/5
A system completes a cycle and returns exactly to its initial thermodynamic state. Which quantity must be zero for the complete cycle?
- A. Net heat absorbed
- B. Change in internal energy
- C. Net work done
- D. Area enclosed on the PV diagram
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2022 Physics Thermodynamics PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2022 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
