AIPMT PRELIMS 2012 Physics Ideal Gas Processes MCQ Question
Type: MCQ-conceptual-Medium-Class 11
One mole of an ideal gas goes from an initial state A to final state B via two processes: It first undergoes isothermal expansion from volume V to 3V and then its volume is reduced from 3V to V at constant pressure. The correct P⁻V diagram representing the two processes is:
Correct Answer
Option A
Detailed Explanation
In an isothermal process, pressure decreases as volume increases, and in a constant pressure process, volume decreases at constant pressure. The diagram showing these characteristics is correct.
