Question

What allows a mixture to be separated by distillation

Answer 1

Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase.

Answer 2

Answer:

difference in boiling points

Explanation:

If you have a mixture of substances, you can heat them up to different temperatures to boil off each substance.  The one with the lowest boiling point will boil off first.  Then you can catch the gas and condense it down to a liquid.
