Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 1/5
Two bodies A and B are separately in thermal equilibrium with a third body C. What follows from the zeroth law of thermodynamics?
- A. A and B are in thermal equilibrium with each other
- B. A and B must have equal masses
- C. A and B must contain equal internal energies
- D. Heat must continuously flow from A to B
Example 3 · difficulty 1/5
A thermometer is placed in contact with a body and its reading becomes steady. What does the steady reading signify?
- A. The thermometer and body have equal internal energies
- B. The thermometer and body are in thermal equilibrium
- C. The thermometer has absorbed all the body's heat
- D. The body has reached absolute zero
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 2018 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 2018 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.
