A packed fractional distillation column will be more effective at separating two closely boiling liquids than an empty one because you have more surfaces for condensation and revaporization of the liquid. A packed fractional distillation column has many more surfaces two allow the mixture of vapors to condense and distill again over and over to effectively separate.
A packed fractionating column is more efficient than an unpacked one because it provides a large surface area for heat exchange between the ascending vapor and the descending liquid. This allows for multiple, successive condenstations and distillations and produces better separation between liquids.

because with fractional distillation it is possible to separate a mixture of liquids whose boiling points are quite close together
Packed and spinning band fractional distillation allow for a greater surface area which improves separation.
I unpacked my lunch.
YES THEY ARE BECAUSE THE UNPACKED FOODS SIT OUT AND THEY SPOIL!!!!!!!!!!!!!!!

No, it cannot.
The ambiguity of his response left us unsure of his true intentions.
Boxes can be unpacked within any land parcel that allows building
it isn't a flat rate deal. It is labor intensive and is billed by the hour.
