NEET 2026 Physics Thermodynamics Questions

Use this page to connect the official 2026 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 1 · difficulty 2/5

An ideal gas expands adiabatically and performs positive work. What happens to its internal energy and temperature?

  • A. Both increase
  • B. Internal energy increases while temperature decreases
  • C. Both remain constant
  • D. Both decrease

Example 2 · difficulty 2/5

During isobaric heating of an ideal gas, 900 J of heat is supplied and the gas performs 300 J of work. What is the increase in internal energy?

  • A. 600 J
  • B. 300 J
  • C. 900 J
  • D. 1200 J

Example 3 · difficulty 1/5

A process follows a vertical straight line on a graph with volume on the horizontal axis and pressure on the vertical axis. Which process is represented?

  • A. Isobaric
  • B. Isochoric
  • C. Isothermal
  • D. Adiabatic

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2026 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 2026 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.
