Meaning of fusion (what is it, concept and definition)

What is Fusion:

Fusion refers to the action and effect of melting or merging. It comes from the Latin fusio , fusionis , which in turn is derived from fusum , supine from fundere , which means 'to melt'.

Merger can designate a union: of ideas, interests or projects. In politics, for example, there may be a motivated merger of parties into a strategy for electoral purposes.

Similarly, one can speak of a merger to indicate the meeting of two or more things in one: two or more powers in a State, or two or more departments in a company.

In addition, in areas such as gastronomy, the combination of styles, flavors and ingredients from different countries and cultures is a gastronomic practice known as fusion.

The same in music when experimenting with the fusion of different genres, for example, symphonic rock or the variety referred to by jazz fusion, which can group salsa, bossa nova or rock with jazz.

Fusion in Physics

Fusion is a concept of Physics that designates the process that a substance undergoes when, having reached its melting point, it passes from the solid state to the liquid, due to an increase in temperature and at a certain pressure.

Melting point

As a melting point we know the temperature at which a fusion is made, considering the pressure. It is constant and invariable when a substance is subjected to normal pressure.

In the same way, its temperature will be constant during the fusion time, that is, once it has reached the melting point, it will not increase.

The melting point varies from substance to substance, and that is why it represents a characteristic property for each element. In water, for example, the melting point occurs at 0 ° C at the pressure of an atmosphere.

There is also a Melting Point.

Melting and boiling

An increase in temperature, beyond the melting point, will bring the substance, already in a liquid state, to its boiling point and, consequently, its passage to the gaseous state will take place.

Melting and solidification

The melting point coincides with the solidification or freezing point, that is, in the opposite direction: the transition from a liquid substance to a solid state by lowering the temperature to a certain pressure.

Nuclear fusion

In Physics, nuclear fusion refers to the exothermic nuclear reaction produced by the union of two light atomic nuclei, giving way to a heavier nucleus and a significant release of energy.

Solar energy, for example, originates from the nuclear fusion of hydrogen that occurs in the Sun, the same occurs in the rest of the stars of the Universe. Nuclear fusion is essential in the reaction of thermonuclear bombs or hydrogen bombs.

Nuclear fusion and nuclear fission

Nuclear fission refers to the nuclear reaction that occurs when the nucleus of a heavy atom divides into two or more nuclei, which will consequently be lighter.

In this sense, nuclear fission will be the reverse process to nuclear fusion, which consists of the union of nuclei of light atoms to form a heavier one. Both, however, are exothermic processes, as they release a significant amount of energy.

Fusion in Chemistry

Within the field of Chemistry, fusion is applied to carry out different tasks, such as the separation of a fusible substance from another infusible, a procedure called separation by fusion or liquefaction; to unite two or more substances in a homogeneous mass, used for alloying metals; as well as for the chemical union of different substances, in order to create a new chemical compound.

Merger of companies

In Commercial Law, a merger refers to the union or integration of two or more companies, companies or legally independent persons, which are diluted to form a new company with a different legal identity than the previous ones, and combining their assets. This type of fusion is called pure fusion.

On the other hand, one of the companies is diluted and the other maintains its identity, increasing the total assets with the merger, called absorption merger.

If they are companies that offer products or services in the same area, and compete with each other, then their merger strengthens them in the face of the market, so it would be a horizontal merger.

If we are in the presence of two companies that do not compete with each other, but could complement each other within the supply chain, such as a construction company and a supplier of construction materials, then it is a vertical merger.
