One way to derive Equation 19.3 depends on the observation that at constant *T* the number of ways, *W*, of arranging *m* ideal-gas particles in a volume *V* is proportional to the volume raised to the *m* power:

*W* ∝*V*^{m}

Use this relationship and Boltzmann’s relationship between entropy and number of arrangements (Equation 19.5) to derive the equation for the entropy change for the isothermal expansion or compression of *n* moles of an ideal gas.
