Module 4 : Thermal analysis

Lecture 21 : Introduction

Differential thermal analysis:

The phenomena causing changes in heat / temperature are

Physical properties

Chemical properties

Adsorption (exothermic)

Oxidation (exothermic)

Crystallization (exothermic)

Chemisorption (exothermic)

Desorption (endothermic)

Reduction (endothermic)

Melting (Endothermic)

Break down reactions (endo or exothermic)

Vaporization (Endothermic)

Solid State reactions (endo or exothermic)

Sublimation (Endothermic)

 

A change in crystal structure (endo or exothermic)
