30 Fusion Examples

The fusion consists of a change of state of a matter in state solid to liquid. This type of transition occurs when the temperature that solid matter acquires increases up to a certain temperature called the melting point. For example: the melting temperature of helium is -272 ° C.

When this point is crossed in the reverse direction, that is, when the temperature of a liquid is lowered until it reaches its freezing point (many times equal to the melting point but with the opposite sign), solidify or freeze the liquid, and the opposite effect occurs. When talking about solidification, it must be taken into account that for this process to occur it is also necessary to increase the pressure of the liquid.

Melting point

The melting point is the temperature at which a solid substance turns into a liquid. This property depends on the pressure and is characteristic of each substance.

Thus, the melting point can be used to identify and determine the degree of purity solids, because when impurities are found, the melting point of a compound drops significantly.

The states and the importance of their changes

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

Solids are characterized by being resistant to changes in shape and volume, with their particles located closely together and organized in most cases.

Liquids, on the other hand, have a fluid and constant shape over a wide pressure range. In most cases they are shaped like the container that contains them.

The differences in the characteristics of each State of aggregation They make the ability to switch from one to the other through a change in temperature or pressure, and in some cases both, so valuable to humans.

Foundry

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

Foundry is the process by which metals or other compounds change from solid to liquid state, usually to be then introduced into a cavity where they solidify and acquire a new shape to something that in its solid form there would have been no way to modify it.

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