What concentrates the chemical components with low-level heat?

• A. Extractors
• B. Processors
• C. Filters
• D. Distillers

Answer: (D)

Distillation concentrates components that have lower boiling points by using gentle, controlled heat to push the more volatile substances into a vapor. As the mixture warms, the component with the lowest boiling point vaporizes first. That vapor travels to the condenser, where it cools and returns to a liquid, giving you a fraction richer in that low-boiling component. By fine-tuning the heat and, if needed, using a fractionating column, you can separate and collect these low-boiling components more cleanly, leaving higher-boiling substances behind. This is what makes distillation the method of choice for concentrating low-boiling-point components, unlike filters (which remove particles), extractors (solvent-based separations), or generic processors.
