I can't figure out how to show that the Clausius entropy

[tex] \Delta S= \int_{T_1}^{T_2} \frac{dQ}{T}[/tex]

is equivalent to the Boltzmann entropy

[tex] S=kln \Omega [/tex]

at thermal equilibrium.

Does anyone know how to do this?

Might want to see how it works for monoatomic ideal gas first, then look for a generalization.
