Question: 1 / 400

What is the process of distillation?

Separating solids from liquids

Evaporating a liquid and then re-condensing it

Distillation is a technique utilized to separate components of a mixture based on differences in their boiling points. The core of the distillation process involves heating a liquid to its boiling point, causing it to evaporate, and then allowing the vapor to cool and condense back into a liquid. This condensed liquid is collected separately, leaving behind other components with higher boiling points or impurities that do not evaporate at the same temperature.

This method is particularly useful in various applications, such as purifying drinking water, separating ethanol from fermented mixtures, or distilling petroleum products. The ability to isolate specific compounds by controlling temperature changes underscores the effectiveness of distillation as a separation technique. The other options do not accurately describe this method's unique process of heating and re-condensing.
