Which process separates liquids based on boiling points and includes condensation of the vapor?

• A. Filtration
• B. Evaporation
• C. Distillation
• D. Chromatography

Answer: (C)

Distillation separates liquids using differences in boiling points, and it involves condensing the vapor back into a liquid. When the mixture is heated, the liquid with the lower boiling point turns into vapor first. That vapor rises into a cooler condenser, where it loses energy and becomes liquid again, and is collected separately. The remaining liquid with the higher boiling point stays behind. This condensation step is what makes distillation effective. Filtration removes solids, evaporation just turns a liquid into vapor without collecting a separate liquid, and chromatography separates substances by how they move through a medium, not by boiling points.
