Question

Describe the relationship between an ensemble, microstates, and entropy.

Answer 1

Here is goes, the relationship between ensemble, microstates and entropy.

An ensemble is a collection of copies of thermodynamic systems, where each has its own possible state or called microstate. These microscopic states have many configurations within thermodynamic properties of the system.

So thus ensembles have almost all the possible states of a system, as it consists virtually infinite states. Now, these microstates can be of any dimension or physical state, such as completely isolated from the environment, with fixed energy in the system.

Another can be of fix temperature microstates and this collection varies from conditions and hence ensemble also varies along with it.

Entropy and these ensembles have a complex relationship in terms of energy distribution and are given by a particular equation.

Now Entropy S is defined by below formula in general in thermodynamics

Where Kb is the Boltzmann's constant and

is the number of microstates consists of that particular ensembles

Hope this relationship details of above mentioned thermodynamic systems and properties, helps you.
