Microstate

Postby Emily Ng_4C » Tue Feb 05, 2019 1:01 pm

What is a microstate and how does it relate to entropy?

From what I understand from lecture, a microstate is a specific arrangement of molecules, a specific set of positions for each molecule in a sample. The more possible microstates or arrangements there are for a sample, the more entropy that sample has.

(If anyone wants to correct/add to that, pls do)

Microstates are specific ways in which the energy of a system can be arranged. The multiple ways the energy can be arranged depends on the atom/molecule arrangements. Entropy is the measure of uncertainty in a system, so the more microstates there are, the higher the entropy.

Knowing the number of microstates gives you the W value to use in the equation S=kB*ln(W).

According to Boltzmann’s equation S=k*ln(W), where W is the degeneracy, what I understand to be the number of possible microstates of the same energy level, more the number of microstates with the same energy level higher the entropy value.

A microstate is a specific arrangement of molecules. Degeneracy is the number of possible microstates/arrangements of a group of molecules, and entropy is calculated using degeneracy.

it is a specific arrangement of the molecules. different micro states have different energy levels and having multiple micro states increases the entropy of a system

When there are more microstates, there is increased entropy. This is because there is greater positional/residual vibration between molecules and that lends to greater disorder.
