NEET Physics Entropy MCQ Question
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?
Entropy
Enthalpy
Internal Energy
Temperature
Correct Answer
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.
