Question

Which one of the following options is not true for hysteresis?

(a) It depends on the nature of the material

(b) It depends on the structural change involved

(c) It doesn’t depend on the experimental conditions

(d) It doesn’t depend on the concentration of the electrode

The question was posed to me by my college director while I was bunking the class.

The query is from Applications of DTA and TGA in chapter Thermal Analysis of Solid State Chemistry

Answer 1

Correct option is (c) It doesn’t depend on the experimental conditions

Easy explanation: Hysteresis depends not only on the nature of the material and the structural changes involved such as difficult transitions involving, for example, the breaking of string bonds are likely to exhibit much hysteresis but also on the experimental conditions such as the rates of heating and cooling.
