Distillation is a seperation technique. On the basis of what physical property are separations achieved? (In other words,differences in what property are used to separate mixtures of compounds when doing a distillation?) Please help!

Boiling point. When one substance boils, it moves off as a gas while the other substance is still trapped as a liquid.

Very basically the compounds are separated as a result of different boiling points.  Components with lower boiling points (higher vapour pressure) are changed to vapour phase after heating, and condensed separately to those components which stayed in liquid phase.

when distilling you're separating compounds using their different boiling points - the compound with the lowest boiling point evaporates first and is collected as condensate. As heating continues compounds in the mix with progressively higher boiling points evaporate and are collected separately.
