Cool down a liquid and it becomes a ...?

• A. Solid
• B. Gas
• C. Liquid
• D. Plasma

Answer: (A)

When a liquid cools, its particles lose energy and move more slowly. As the temperature reaches the freezing point, the particles arrange into a fixed, orderly pattern and the substance becomes a solid. So the result of cooling a liquid is a solid. Gas would come from adding energy (heating) to turn a liquid into vapor, not from cooling; plasma is a high-energy, ionized state not produced by ordinary cooling; the liquid state would only persist if cooling didn’t go past the melting point.
