Boltzmann Equation

Postby Siddiq 1E » Sat Feb 08, 2020 8:40 pm

Can someone explain when the boltzmann equation is more useful than the other methods to calculate entropy?

Only when we consider degeneracy and the question mentions something about possible energy states.

Yep, in terms of molecular states the Boltzmann equation will be useful for calculating entropy (statistical). The other equation for entropy is good for thermodynamics as a whole.

As mentioned above, the Boltzmann Equation is helpful when we are given or can calculate degeneracy (W). The Boltzmann equation also just solves for S and not delta S, whereas the other equations solve for delta S or a change in S
