Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Melting
Concept:

States of matter undergo distinct, direction-specific phase transitions.

Formula:

Not applicable.

Solution:

  • Liquids can be cooled down to their "Freezing point" to become solids.


  • Liquids readily "Diffuse" into one another.


  • Liquids serve as solvents generating "Osmotic pressure" across semipermeable membranes.


  • However, "Melting" is explicitly defined as the phase transition from a Solid to a Liquid. A substance that is already in the liquid state cannot melt. Therefore, melting is a property of solids, not liquids.


Why other options are incorrect:

The other options are standard physical or colligative properties inherently applicable to substances in the liquid state.

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.
