    Thermal analysis
     A group of techniques in which a property of the 
     sample is monitored against time or temperature
     while the temperature of the sample, in a specified 
     atmosphere, is programmed.
      Introduction  
       Thermal methods of analysis include a group of
         techniques in which change in physical property of a
         material is measured as a function of temperature while
         the substance is subjected to a controlled temperature
         programme.
       In modern era the new materials are studied with
         respect to – composition, stability, chemical reactions
         and dynamic properties.
       Thermal methods are useful for these kind of analysis.
       These methods also provide information about the
         structure,  composition,    purity   and the temperature
         phase change of a material.
