Question
Chapter 31, Problem 31.7QAP
Interpretation Introduction
Interpretation:
The physical changes associated with endothermic or exothermic peaks in differential scanning calorimetry and differential thermal analysis are to be listed.
Concept introduction:
Determination properties of materials are done on the basis of change of temperature and it is known as thermal analysis. Many methods are there as example DSC or DTA etc.
