Concept:Volume is defined in physics as the 3D space occupied by matter. Macroscopically, it is both an "Extensive property" (depends on mass) and a "State function" (independent of path).
Solution:- Note on Exam Fidelity: This specific past paper question contains severely flawed options, and its official answer key marks Volume as a Path function. This is objectively incorrect in physical chemistry.
- A true path function is Work (\( W = P\Delta V \)), but Volume itself (\( V \)) has fixed coordinates in any state diagram and is unequivocally a State Function.
- We have mapped the Answer Key (C) for strict historical grading accuracy, but logically, Volume is neither an intensive property, a path function, nor an isolated system.
Why other options are incorrect:It is not an intensive property because volume strictly scales with the amount of matter (making it extensive). It is not entropy (a completely different thermodynamic property).
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
