Question

What is the range of the rate in ◦Cmin^-1 required during the heating process in TGA?

(a) 1-20

(b) 25-50

(c) 100-200

(d) 150-1000

This question was posed to me in semester exam.

I would like to ask this question from Thermogravimetric Analysis topic in portion Thermal Analysis of Solid State Chemistry

Answer 1

The correct choice is (a) 1-20

Easiest explanation: In the process of TGA thermogravimetric technique, the sample usually a few milligrams in weight, is heated at a constant rate, typically in the range of 1-20 ◦Cmin^-1 and a constant weight Wi, until it begins to decompose at temperature Ti.
