Explanation:

Gases: more space therefore meaning that particles in the gas have the highest Kinetic energy therefore moving faster all around.

Liquid: they have more kinetic energy than liquid,but they have some space for movement so they collide each other quicker due to lack of space.

solids: They have least kinetic energy as they have no space at all meaning particles can move around and only just vibrate against each other.

Fractional distillation

Explanation:

The best way to separate the mixtures out is through the process of fractional distillation.

In fractional distillation, liquid - liquid mixtures are separated based on the differences in boiling point of their components. Let us examine the boiling points of the component of the mixtures:  

     Ethanol                  78⁰C

     Glycerol                290⁰C

     Ethylene glycol     197.6⁰C

     Methanol               64.7⁰C

     Water                     100⁰C

We see that the liquids in the mixture have different boiling points. In this process, the mixture is heated in a distillation column. When the boiling point of any component is reached, it will rise up in the column and can be channeled to a condenser where it is cooled and collected.

The liquid with the least boiling point is first separated with the one with the highest boiling is recovered last:

   Order of recovery;

               Methanol               64.7⁰C

               Ethanol                  78⁰C

                Water                    100⁰C

               Ethylene glycol     197.6⁰C

                Glycerol                290⁰C
