Question

Which of the following method is described by the diagram given below?

(a) Hydrothermal analysis

(b) Thermogravitric analysis

(c) Heat analysis

(d) Differential thermal analysis

I had been asked this question during an interview for a job.

This interesting question is from Differential Thermal Analysis and Differential Scanning Calorimetry topic in section Thermal Analysis of Solid State Chemistry

Answer 1

Correct answer is (d) Differential thermal analysis

To explain: The arrangement normally used in DTA, differential thermal analysis. Sample and reference are placed side by side in a heating block which is either heated or cooled at a constant rate, identical thermocouples are placed in each and are connected ‘back to back’.
