r'''Mass heat capacity of the chemical at its current phase and
        temperature, in units of [J/kg/K].

        Utilizes the object oriented interfaces
        :obj:`thermo.heat_capacity.HeatCapacitySolid`,
        :obj:`thermo.heat_capacity.HeatCapacityLiquid`,
        and :obj:`thermo.heat_capacity.HeatCapacityGas` to perform the
        actual calculation of each property. Note that those interfaces provide
        output in molar units (J/mol/K).

        --------
        >>> w = Chemical('water')
        >>> w.Cp, w.phase

        >>> Chemical('palladium').Cp
