Fusion refers to the transformation of a solid into a liquid.
A physical change is the melting of ice. Water (H2O) appears to alter when it turns from a liquid state to a solid state (ice). However, this shift is just physical, as the constituent molecules still consist of 11.19% hydrogen and 88.81% oxygen by mass.
The idea of a substance changing from its solid form to its liquid state serves as the foundation for this query. In order to break the bonds in solid state, this procedure includes the absorption of heat energy. As a result, the material disintegrates and turns into a liquid. Fusion is the name of this process.
