Original practice preview

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

Example 1 · difficulty 1/5

Bodies X and Y are each placed separately in thermal contact with body Z, and after some time neither X nor Y shows any further net exchange of heat with Z. What follows directly from the zeroth law of thermodynamics?

A. X and Y are in thermal equilibrium with each other
B. X and Y must contain equal quantities of heat energy
C. Heat will now begin to flow spontaneously from X to Y
D. X and Y must also have equal masses and equal volumes

Example 2 · difficulty 2/5

An ideal gas is sealed inside a perfectly rigid steel vessel and 250 J of heat is supplied to it. The change in internal energy of the gas is:

A. zero, because the volume of the gas does not change
B. less than 250 J, because part of the heat is spent in doing expansion work
C. 250 J, because no work is done by or on the gas
D. not determinable unless the molar specific heat of the gas is known

Example 3 · difficulty 2/5

An isotherm and an adiabat of an ideal gas intersect at a point on a P–V diagram. At that point, the magnitude of the slope of the adiabat is greater than that of the isotherm by a factor of:

A. (γ − 1)
B. γ
C. 1/γ
D. they have exactly equal slopes at the intersection point

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

How many Thermodynamics NEET questions are available?

NeetVellum currently publishes 200 original, verified questions across the linked canonical chapter.

How should I revise Thermodynamics for NEET?

Attempt questions before rereading, classify each miss, repair the specific concept, and re-practice after a delay until the error pattern disappears.
