Thermal Analysis

INTRODUCTION

Thermal methods are mainly used for the determination of physical or chemical change of substances as a function of temperature. Based on the change in the physical property, the thermal analytical methods named as different. They are as follows:

Change in physical property	Name of the method
Mass	Thermogravimetry
Temperature	Differential thermal analysis
Heat flow (enthalpy)	Differential scanning calorimetry

These methods are mainly used in the polymer analysis and solid state analysis.

Maxwell–Boltzmann distribution: This is for the molecular speeds for different molecules with different masses and different temperatures. The light molecules have the high molecular speed than the heavy molecules. ...
