Problem
Which of the following shows the correct sequence of the changes of state involved in distillation? a. boiling, condensing b. condensing, boiling c. evaporation, cooling d. boiling, coolingIntuitive explanation
Distillation is fundamentally about separating liquids by exploiting their different boiling points. The key insight is recognizing that you must heat a liquid until it becomes a gas (evaporation), then cool that gas back down into a liquid (condensation)—the reverse of the path you took. Understanding this two-step state change sequence, and why each step happens at a specific temperature, is what lets you identify the correct answer.
