What is the change of state from a liquid to a solid called?

The change of state from a liquid to a solid is called freezing. This process occurs when the temperature of a liquid drops to its freezing point, causing the particles within the liquid to lose energy and arrange themselves into a fixed structure, thus forming a solid.

During freezing, the kinetic energy of the particles decreases, leading to a reduction in movement and allowing the attractive forces between them to take effect. As a result, the particles are locked into place, which is characteristic of solid states. Understanding this process is crucial in studying phase changes and thermodynamics in physics.
