def Cps(self):
        r'''Solid-phase heat capacity of the mixture at its current temperature
        and composition, in units of [J/kg/K]. For calculation of this property
        at other temperatures or compositions, or specifying manually the
        method used to calculate it,  and more - see the object oriented
        interface :obj:`thermo.heat_capacity.HeatCapacitySolidMixture`; each
        Mixture instance creates one to actually perform the calculations. Note
        that that interface provides output in molar units.
