How can I prove that the entropy change is intrinsically positive?

Given two systems with both of the heat capacities are independent of temperature.

You need to explain a little better. What does "intrinsically positive" mean in this context?

Regarding two systems with both of the heat capacities are independent of temperature...huh? Put yourself in my place reading this and trying to envision what your are talking about. You need to present a more precise and complete description.
