Our goal is to achieve in a condensed way, the resolution of some difficulties about the conceptual foundations of Thermodynamics-problematic ideas are identified and analysed. These difficulties have been presented and published in several and incompatible ways but the subject is still controversial. Why is this controversy still unsolved or-and this is stranger-why do some authors refuse the existence of difficulties although the existence of incompatible formulations is a fact? How can a resolution be obtained after the problem has been clearly identified? The difficulties and the solution considered are related to the followings concepts: 1. The several concepts of Heat. 2. The several concepts of Force. 3. The First Law and the concepts presented on points 1 and 2. 4. The several concepts of reversibility and the concept of quasi-static transformation. 5. The introduction of entropy in a simple and straightforward way with a physical interpretation to circumvent and clarify all the difficulties identified-we propose an energy-entropy principle.
