Melting point


What is the melting point? Definition and explanation ...

Of the melting point or the melting temperature indicates the temperature at which a chemical changes from a solid to a liquid aggregate state.
The simplest example of this is water: the melting point is 0 ° C. Water below this temperature is present as ice (solid state of matter). With reaching or exceeding the melting temperature, ie at least 0 ° C, the ice melts into water (liquid state of matter). Impurities or added substances such as e.g. Salt or alcohol can lower and raise the melting point.
