To **calculate ΔS _{fus} and ΔS**

$\overline{){{\mathbf{\Delta S}}}_{{\mathbf{fus}}}{\mathbf{=}}\frac{{\mathbf{\Delta H}}_{\mathbf{fus}}}{{\mathbf{T}}_{\mathbf{m}}}}$ $\overline{){{\mathbf{\Delta S}}}_{{\mathbf{vap}}}{\mathbf{=}}\frac{{\mathbf{\Delta H}}_{\mathbf{vap}}}{{\mathbf{T}}_{\mathbf{b}}}}$

Using the following data,

Calculate ?Sfus and ?Svap for Cs.
