The following figure represents the result of a calorimetry experiment exploratory scanning (DSC) conducted with a polyethylene sample terephthalate (PET). The experiment consists of heating at a constant rate (first heat) followed by cooling (cool), also at a constant rate. Identify, in each of the curves, the nature of each thermal event (fusion, Tg, ...).
