Which word refers to the process of making something purer through boiling and condensation?

The term that refers to the process of making something purer through boiling and condensation is "distill." This process typically involves heating a liquid to create vapor and then cooling that vapor to form a liquid again, effectively separating and purifying components based on their differing boiling points.

In distillation, impurities can be left behind when the desired substance is vaporized and then condensed back into liquid form, leading to a purer product. It is a key technique used not only in chemistry but also in industries like beverage production, petroleum refining, and production of essential oils.

Other options refer to related but distinct processes. "Evaporate" means to change from a liquid to a vapor, but it does not imply the process of condensing or purification. "Refine" generally implies a broader process of removing impurities or unwanted elements from a substance but does not specifically involve boiling and condensation. "Condense" refers to the change from vapor to liquid and does not encompass the entire distillation process, including the initial boiling stage. Thus, "distill" is the most accurate term for this purification method.
