Description

Experiment C1.6.2.1 takes a closer look at sulphur. Sulphur has the ability to form chains and rings, and that makes it the element with the most modifications. Those modification changes are studied by differential thermal analysis. For this purpose, a sample of sulphur is heated and its temperature is measured. During the modification changes, the temperature of the sample no longer increases as compared with a control substance. There is no measurable temperature increase until the modification change is complete.
