Solidification is the process by which a substance changes from a liquid or gas state to a solid state as it loses heat. During this phase transition, particles lose kinetic energy, arranging themselves into a more ordered and rigid structure.
Commonly observed in freezing or crystallization, solidification plays a fundamental role in material science, manufacturing, and geophysics.
Understanding the solidification process is crucial for controlling the properties of materials, from metals to polymers, and for studying natural phenomena like the formation of ice in freezing water.
