Microstates and macrostates<br />

There are 15 microstates.<br />

IG-10<br />

Each microstate is a way to distribute the energy.<br />

All microstates belong to the same macrostate.<br />

The macrostate has 4 quanta of energy.<br />

The 4-quanta macrostate can also be categorised into types:<br />

•(4,0,0) type 400<br />

•(2,1,1) type 211<br />

•(3,1,0) type 310<br />

•(2,2,0) type 220<br />
