Thermal Analysis Techniques
Differential Scanning Calorimetry (4.6) Differential scanning calorimetry (DSC) is a way of measuring energy changes associated with physical transitions.
Heat and Temperature. The difference Heat – the energy that flows from hot to cold. Measured in Joules (J) or calories (cal). Temperature – measure of.
