Original practice preview

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

Example 1 · difficulty 3/5

Two moles of an ideal gas at 300 K expand isothermally and reversibly until the volume becomes twice its initial value. Taking R = 8.3 J K⁻¹ mol⁻¹ and ln 2 = 0.693, the work done by the gas is approximately:

A. 1.73 × 10³ J
B. 6.90 × 10³ J
C. 4.98 × 10³ J
D. 3.45 × 10³ J

Example 2 · difficulty 2/5

For a monatomic ideal gas, the ratio of the molar specific heat at constant pressure to the molar specific heat at constant volume (γ = Cp/Cv) is:

A. 7/5
B. 9/7
C. 5/3
D. 3/2

Example 3 · difficulty 4/5

A reversible refrigerator maintains its compartment at 250 K while the room is at 300 K. If it extracts 750 J of heat from the compartment per cycle, the minimum work that must be supplied per cycle is:

A. 50 J
B. 150 J
C. 125 J
D. 750 J

Frequently asked questions

Are these official NEET 2017 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 2017 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.
