Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

Systems X and Y are separated by an insulating wall, while each can exchange heat with system Z through conducting walls. After equilibrium is established, which statement is correct?

A. Y must have a greater internal energy than X
B. X must have a greater temperature than Y
C. X and Y necessarily have the same temperature
D. X and Y exchange heat directly through the insulating wall

Example 2 · difficulty 1/5

Which set contains only thermodynamic state variables for a simple gas in equilibrium?

A. Work, volume and heat
B. Heat, work and temperature
C. Heat, pressure and work
D. Pressure, volume and temperature

Example 3 · difficulty 1/5

For a fixed amount of an ideal gas, which relation serves as its equation of state?

A. PV = nRT
B. P + V = nRT
C. PV = nR/T
D. P/T = nRV

Frequently asked questions

Are these official NEET 2019 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 2019 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.
