Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Isothermal process
1. Concept:

Boyle's Law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume, provided the temperature remains absolutely constant.

2. Formula:

$$P \propto \frac{1}{V} \quad (\text{at constant } T)$$

3. Solution:

  • Because Boyle's law strictly requires a constant temperature to be mathematically valid (\(PV = \text{constant}\)), the thermodynamic environment must enforce this.


  • A process that maintains a constant temperature is defined as an isothermal process.


4. Why other options are incorrect:

Isobaric processes enforce constant pressure (Charles's Law). Isochoric processes enforce constant volume (Gay-Lussac's Law). Adiabatic processes allow temperature to fluctuate.

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.
