Logic functions

I am new to comsol, and I am making a 2d model of a tank exposed to a heat flux on the top plate, in order to heat a phase changing material inside the tank. Fins are used to enchance the heat transfer.
My problems is:
How do I define the special solar salt I am filling the tank with (a mix of KNO3 and NaNO3)? More precisely; I want to use logic functions so that the Cp-value is changing depending on the temperature of the salt. (for T<110, Cp=0.75 etc) Where can I do that?
Thank you in advance,
Marie.
