What is the phase change from liquid to solid called?

• A. Freezing
• B. Melting
• C. Condensation
• D. Vaporization

Answer: (A)

This question tests your understanding of phase changes, specifically what happens when a liquid loses heat and becomes a solid. The phase change from a liquid to a solid is freezing. As heat is removed, the particles slow down and arrange into an orderly, fixed structure, releasing energy to the surroundings in the process. Melting is the opposite change, where a solid gains heat and becomes a liquid. Condensation is gas turning into a liquid, and vaporization is liquid turning into a gas. So the liquid-to-solid change is freezing.
