AIPMT PRELIMS 2011 Chemistry Laws of Thermodynamics MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Which of the following is correct option for free expansion of an ideal gas under adiabatic condition?
A
q = 0, ΔT < 0, w ≠ 0
B
q = 0, ΔT ≠ 0, w = 0
C
q ≠ 0, ΔT = 0, w = 0
D
q = 0, ΔT = 0, w = 0
Correct Answer
Option D
Detailed Explanation
For an ideal gas, during free expansion, there is no heat exchange (q = 0), no work done (w = 0), and no change in temperature (ΔT = 0).
