Distillation is a separation technique that exploits differences in volatility among the components of a liquid mixture. The mixture is heated to a temperature where the more volatile component vaporizes while the less volatile components remain largely liquid; the vapor is then routed to a condenser where it is cooled and returned to liquid form (the distillate), leaving behind the less volatile components (the residue). Simple distillation suffices when volatility differences are large; fractional distillation employs a fractionating column to provide multiple vaporization-condensation cycles for closer-boiling mixtures. The process is governed by vapor-liquid equilibrium principles, particularly Raoult's law for ideal mixtures and the concept of relative volatility for non-ideal systems.

Definition
Why it is in scope
A separation process in which components of a liquid mixture are separated based on differences in volatility: the mixture is heated to produce vapor richer in the more volatile component, and the vapor is then condensed back into liquid form. Human-made as both a practiced technique (heating, condensing, collecting) and a conceptual framework for purification by differential volatility.

Distillation IS a specific kind of method: a systematic procedure for separating components of a mixture based on volatility differences. A competent speaker would say 'distillation is a kind of method (or technique).' The note pins the sense of method as a systematic procedure for achieving a specific result.
