Why temp down than its boiling temp in under vacuum distillation?

The boiling point of a liquid is closely related to the atmospheric pressure in which it finds itself. Basically, the lower the atmospheric pressure (whether it is 'air' or any other gases) the lower the boiling point.
For example, water will boil at much less than 100degrees celcius at the top of Mount Everest.

Explain how fractional distillation is used to separate petroleum into components?
you use metromorphism distillation to separate the fractions
What products come from fractional distillation?
fractional distillation is usually use to separate the constituents of crude oil, into petroleum, jet fuel, asphalt, kerosene, and others. Most oil based products are separated by fractional distillation.
Why does the temperature fall down towards the end the fractional distillation?
why doesthe temprature fall down towards the end of the fractional distillation
In distillation the water inlet is down why?
because its not up
What does fractional distillation mean in chemistry?
Fractional distillation is a manufacturing process that separates the different components (i.e. fractions 1/2 in a chemical mixture according to their different boiling points. The liquid is raised to boiling and vapors pass through a tubular column where temperature is gradually lowered along its length. Components (fractions) with a higher boiling point condense on the column and return to the solution. Fractions with a lower boiling point pass through the column and are collected. Gasoline, kerosene and naphtha are fractions separated from crude oil using fractional distillation.Here's more in simple,the basic principle of fractional distillation is of using the different boiling points of elements(parts) in a compound(a mixture). A fractional distillation process is done in a cylinder which has different compartments having different temperature points. When the mixture is kept in the cylinder, the elements which have the same boiling point as in the compartment it is in, it vaporizes and moves out through a pipe. The mixture goes on vaporizing as the temperature increases and at last all the elements are removed in separated drums where they are condensed and brought back to their normal state.Another way of putting it is:Fractional distillation differs from distillation only in that it separates a mixture into a number of different parts, called fractions. A tall column is fitted above the mixture, with several condensers coming off at different heights. The column is hot at the bottom and cool at the top. Substances with high boiling points condense at the bottom and substances with low boiling points condense at the top. Like distillation, fractional distillation works because the different substances in the mixture have different boiling points.The simplest way is:Fractional distillation is a form of distillation which is used when more than two liquids with different boiling points are to be separated.
What is disillation?
distillation is a way of separating elements by boiling mixtures up and then cooling them down.
Is an orange sqeezed to make orange juice is example of distillation?
No. No, boiling the water out of it would be distilling it down.

Explain the differences between fractional and simple distillation which is more efficient how the efficiency could be enhanced What is the purpose of adding boiling stones?
The difference is that simple distillation will be used to separate substances within mixtures that have significantly different boiling points; whereas, with fractional distillation, the boiling points are closer and separation must be cared for differently. This is the reason why you must employ the use of an additional piece of apparatus called the fractionating column when undergoing fractional distillation. Based on what is stated above, the more efficient method would have to be Fractional Distillation because it essentially separates the parts of the mixture much more precisely. You could enhance fractional distillation by using boiling stones. The reason for adding the boiling stones is to calm down the boiling of the liquid mixture. You really do not want the boiling to become too violent as is the case with "bumping" which is when the air pressure inside the liquid increases so rapidly that it will literally BUMP the glass while it is trying to expel the excess air pressure. Normally only th air will be relieced out from the opening of the container such as the top (ie. the surface of the liquid), but too much air and too little surface area at the top will cause air to be reliese radially outward and strike the sides of the container. Just try boiling eggs real fast with the stove on high and never turn it down; you'll see it happen.

cause it goes upand down. thats how it works

Can we produce drinking water by boiling sea water to catch the steam and cool it down and if so why sailors in the ancient times didn't do that when they were short of fresh water?
Distillation is a method to obtain drinking water but in the past necessary installations were not known.
What is destructive distillation of coal?
Destructive distillation of coal is heating coal in a retort until its chemical structure breaks down (destructive or nonreversible). The products are: coal gas, coal tar, and coke. Ordinary distillation is reversible by just remixing the products. Destructive distillation is nonreversible.
