Experiment with Crude Paraffin

During this experiment we were observing the features of crude paraffin. Paraffin was in the grain form. We put as many grains as possible into the measuring cylinder to have 2 liters of a saturated solution after warming up. There were no other measurable external influences. We expected temperature "jumps" and big differences. We were also observing solidifying of the paraffin. There were temperature jumps that were comparatively large, which is explained by structure of paraffin, an amorphous material. During the solidifying there were no similar "temperature jumps" after similar time. The crude paraffin started to be stiff in temperature around 55 oC without external extensions.
