Understand that distillation is a separation technique based on differences in volatility between components in a mixture.
Recall that volatility is related to the boiling point of a substance; substances with lower boiling points vaporize first.
Recognize that during distillation, the mixture is heated until one component vaporizes, then the vapor is condensed back into liquid form separately.
Identify that the key property enabling this separation is the difference in boiling points of the components in the mixture.
Note that other properties like solubility, magnetic properties, or density are not the basis for separation by distillation.
