Answer:
Nuclear fusion, Alloy, and Combustion.
Explanation:
Nuclear fusion: This process is given by the union of light atoms in other heavier ones for its later "bombardment" with some element that causes its expansion in an accelerated way.
Nuclear fusion releases immense amounts of energy. It is currently used in the generation of energy and the creation of warfare artifacts.
Alloy: In metallurgy, it is called alloy to the process and the material obtained with the combination of a metallic element with another one, be this a metal or not.
It serves to obtain materials more resistant, stronger to corrosion. Bronze, steel, and brass are examples of alloys of materials with iron.
Combustion: Any chemical reaction that rapidly oxidizes a fuel element combined with an oxidizer (such as oxygen) to produce heat is classified as combustion.
It is a chemical process relevant to humans, as this discovery has improved the lives of humans. Combustion is present in motor vehicles, gas cookers, and heating.
Have a nice day!
