In a microcanonical ensemble, a system A of fixed volume is in contact...
In a microcanonical ensemble, the total energy (E) of the system A (which includes both A and B) is fixed and conserved. System A cannot exchange energy or particles with the surroundings, so the correct option is:
Option A: A can exchange neither energy nor particles with B.
Therefore, the correct answer is Option A.

In a microcanonical ensemble, a system A of fixed volume is in contact...
Explanation:
Microcanonical Ensemble:
In a microcanonical ensemble, the system A is isolated and has fixed values of energy, volume, and number of particles. The system is in contact with a reservoir B, which is large enough to be considered infinite.
Exchange of Energy and Particles:
- In a microcanonical ensemble, the system A cannot exchange energy with the reservoir B because the total energy of the system is fixed.
- Similarly, the system A cannot exchange particles with the reservoir B because the number of particles in the system is also fixed.
Fixed Volume:
- Since the system A has a fixed volume, it cannot exchange particles with the reservoir B as well.
Conclusion:
Therefore, in a microcanonical ensemble, the system A can exchange neither energy nor particles with the reservoir B. The system is isolated and maintains constant values of energy, volume, and number of particles.
