Microcanonical ensemble

The microcanonical ensemble is a way scientists describe a system in statistical mechanics where energy, volume, and particle number are fixed. Imagine a sealed box with a set amount of energy spread among particles; all possible arrangements of particles that keep the energy constant are considered equally likely. This approach helps predict the system's behavior by analyzing the number of these arrangements, providing insight into thermodynamic properties like entropy and temperature without external influence. It is fundamental for understanding isolated systems in thermal equilibrium.
