Original practice preview

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

Example 1 · difficulty 2/5

A fixed amount of a simple ideal gas is in an equilibrium state. If its volume and temperature are specified, what can be determined using the equation of state?

A. The heat supplied along every possible path
B. Its pressure
C. The work done in reaching the state
D. The duration of the process

Example 2 · difficulty 1/5

Which quantity has a definite value for each equilibrium state and is therefore a state function?

A. Heat supplied
B. Work done by the system
C. Internal energy
D. Area traced during a process

Example 3 · difficulty 1/5

Why is heat supplied to a system not regarded as a thermodynamic state variable?

A. Heat always has a negative value
B. Heat can be defined only at absolute zero
C. Heat is identical to temperature
D. Heat depends on the path used to change the state

Frequently asked questions

Are these official NEET 2020 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 2020 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.
