Let us calculate :

**Conjugated Fields:**- Variable
*X*is a conjugated field to*x*_{i}, if If one is extensive, another is intensive! **Examples:**- pressure (
*x*) & volume (*X*), magnetization (*x*) & field (*X*),...

If we know partition function, we can calculate averages!

Second derivative:

This is *mean squared fluctuation!*
