Type: MCQ-diagram based-Medium-Class 11
A diagram shows two containers separated by a movable partition. Initially, gas A is in the left container and gas B in the right. When the partition is removed, the gases mix. Which thermodynamic quantity best describes the change observed when the gases mix?
A
Entropy
B
Enthalpy
C
Internal Energy
D
Temperature
Correct Answer
Option A
Detailed Explanation
The mixing of gases leads to an increase in disorder, hence an increase in entropy, as described in the context of entropy changes during diffusion.
