Which term describes the change from liquid to solid?

• A. Melting
• B. Freezing
• C. Freezes
• D. Solidification

Answer: (B)

The change from liquid to solid happens when a liquid loses enough energy to form a fixed, orderly arrangement of particles. This process is called freezing. As the liquid cools below its freezing point, the particles slow down and lock into a rigid structure, releasing energy to the surroundings in the process. Freezing is the most common term used to describe this direction of change, though solidification can also describe the same transition in broader terms. Melting describes the reverse change (solid to liquid), and “freezes” is simply a verb form and not the standard name for the process.
