Question
Chapter 4, Problem 4B.3DQ
Interpretation Introduction
Interpretation: The use of differential scanning colorimetry (DSC) in identifying the phase transitions has to be stated.
Concept introduction: Differential scanning colorimetry is an analytical technique which is used to track the amount of heat which is necessary to increase the temperature of the sample as a function of temperature. In this technique, both the sample and the reference are kept at nearly identical temperature.
