Distillation separates or purifies liquids, while evaporation changes the form of a substance.
Distillation is a purification process for liquids. It can involve condensation and/or evaporation steps. Evaporation is the vaporization of a liquid. During evaporation, liquids become gases, so the phase of matter has changed. Both may be intentional, and both require the use of tools―even if that tool is as simple as a pot.
B Distillation involves the use of implements, while evaporation only requires heat.
C One is intentional in scope, while the other occurs during other practices.
D Distillation and evaporation have no primary difference; they are the same process.
