What is solidfication in science?

Answer 1

Merriam-Webster defines solidification as "to make solid, compact, or hard". Science has no unique definition for it. Essentially it means the conversion of a liquid or gas to a solid form, often by crystalization. The result is that the atoms and molecules are locked in place and don't wander about in the substance. Freezing of water is a familiar type of solidification.

It may be a rapid change of states, for example, water becoming ice, or it may be just a gradual change where a substance hardens as it cools, such as glass.

Answer 2

Solidification is the process by which a liquid transforms into a solid state when it cools down below its melting point. It involves the rearrangement of atoms or molecules from a disordered to an ordered structure, resulting in the formation of a solid material with a fixed shape and volume. Solidification is a common phase transition in materials science and is crucial in various industrial processes, such as casting and crystallization.
