what is the thermometric analysis ? is i took it in under graduated

[Arkcon]

Briefly, thermometric analysis is analytical method, developing something like a profile for a substance that is gradually heated or cooled.  As I understand it, a sample may melt, decompose, oxidize, or react with other components.  This changes the profile, which is useful to determine identity, or purity.  To me however, its very much a "black box" -- I do what I'm told, and I get a heating profile, or I don't and I report that.  Sorry, I can't find a better answer in Wikipedia, but someone on our forum may come up with a better resource for you.  I don't think its often taught at the undergraduate level, but its a worthwhile thing to learn.

Here's a good article on the general topic:
