Concept:Thermodynamic and physical properties (like boiling point, heat of vaporization) are intensive properties heavily dependent on the strength of intermolecular forces holding the molecules together.
Formula:$$ n = \frac{m}{M} $$
Solution:- Boiling point, heat of sublimation, and heat of vaporization all quantify the physical energy required to pull molecules apart against their dipole-dipole attractions. Stronger forces mean higher values.
- The concept of "Moles" is a fundamental measurement of the sheer quantity or amount of a substance, not its chemical behavior or bonding strength.
- Changing the polarity or intermolecular forces of a liquid will never alter the number of moles present in a closed container.
Why other options are incorrect:Options A, B, and C are entirely governed by intermolecular forces, so they will directly change if the forces change.
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.
