Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Isochoric
1. Concept:

Thermodynamic processes are named based on the property that remains rigid or unchanging throughout the physical transformation.

2. Formula:

$$\Delta V = 0 \implies W = 0$$

3. Solution:

  • The prefix 'iso-' means equal or constant.


  • The suffix '-choric' pertains to space or volume.


  • Therefore, an Isochoric process is defined strictly as a thermodynamic change where the container's volume remains completely unchanged.


4. Why other options are incorrect:

Isobaric means constant pressure. Isothermal means constant temperature. Adiabatic means zero heat transfer.
