NEET 2020 Chemistry Adiabatic Processes MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The correct option for free expansion of an ideal gas under adiabatic condition is:
A
q < 0, ΔT = 0 and w = 0
B
q > 0, ΔT > 0 and w > 0
C
q = 0, ΔT = 0 and w = 0
D
q = 0, ΔT < 0 and w > 0
Correct Answer
Option C
Detailed Explanation
In free expansion, no work is done (w = 0) and no heat is exchanged (q = 0), so the temperature change is zero (ΔT = 0).
