Refresh the page or contact the site owner to request access. The crystalline structure is destroyed and the solid material melts. A single substance, instead of having a single melting/freezing point, will have more of a moving point on a line or a curve. This is called the freezing point, and it will happen at the same temperature as the melting point, because it is the same threshold that is being passed. Compared to other physical values the change in light transmission can easily be determined and can therefore be used for melting point detection. Learn about how distillation works by studying its process and procedures. At the melting point not only the aggregate state changes; quite a lot of other physical characteristics also change significantly.
