30 Examples of Fusion

The fusion  consists of a change of state of a matter in solid to liquid state . This type of transition occurs when the temperature that the material acquires increases up to a certain temperature. 

When this point is crossed in the reverse direction, ie when a liquid lowers its temperature until it reaches it, it solidifies, the opposite effect occurs.

Melting point

The level of temperature at which chemical fusion occurs is precisely called the melting point , and is related to the level of external pressure at which it is located.



The melting point has a function in the characterization of solids, which is to determine the degree of purity that matter possesses: when impurities are found, the melting point of a compound drops significantly, so that the Fusion compliance when the theoretical value is reached indicates the purity of the solid.

The states and the importance of their changes

The solid state and the liquid are the two in which the objects are perceptible by the sense of touch:

Solids are characterized by resistance to changes in shape and volume, with particles found in unity and satisfactorily organized

Liquids, on the other hand, have a fluid and constant form in a wide range of pressure. The differences in the characteristics of each state of aggregation make it so valuable for the human being the possibility of passing from one to the other by means of a change in temperature.


There are many areas in which chemical fusion is used, but among all one stands out, which is that of metallurgy.

It is called casting the process by which metals change from the solid to the liquid state , usually to be then introduced into a cavity where it solidifies, giving a new shape to something that in its solid form there had been no way to modify it.

For that, sometimes chemical processes must be carried out that allow reaching very high temperatures , which demand these foundries.
