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.

What do you observe if you start heating the two miscible liquids by distillation?
As the two miscible liquids are heated, the one with the lower boiling point will vaporize first. The vapor will rise into the distillation column, where it will condense back into liquid form as it cools down and collects in the receiving flask. This process enables the separation of the two liquids based on their boiling points.
Explain how fractional distillation is used to separate petroleum into components?
Fractional distillation separates petroleum into components based on their boiling points. The crude oil is heated to vaporize, then the vapors pass through a fractionating column where they condense at different heights based on their boiling points. The different components, like gasoline, diesel, and kerosene, are collected at different heights and can be further processed.
Why does the temperature fall down towards the end the fractional distillation?
why doesthe temprature fall down towards the end of the fractional distillation
Crude oil is broken down by heat vaporized and allowed to condense into various liquids such as gasoline what is this process is called?
This question is misguided. Crude oil is first processed by heating it, which separates it into simpler mixtures called fractions which are of considerably more use than the original crude. This process is called fractional distillation, but it is NOT breaking anything down, merely sorting out substances which are already there. Some of the fractions, often those with higher boiling points may be broken down by cracking, a chemical process which also uses heat, often with a catalyst, and which produces smaller molecules such as those of petrol and ethene.
Does distillation produce a chemical or a physical change in petroleum?
it is a physical change
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.
Can boiling point of acetone be lowered if placed in a vacuum?
Yes, the boiling point of acetone can be lowered if placed in a vacuum, as reducing the pressure lowers the boiling point of a substance. This is because at lower pressure, there is less external pressure pushing down on the liquid molecules, allowing them to escape into the vapor phase more easily.

Why don't the hydrocarbon molecules breakdown into hydrogen and carbon atoms when they are heated during fractional distillation?
Hydrocarbons do not break down into their elements when fractionally distilled because the minimum energy necessary for separating the hydrocarbons into their elements is not available from the thermal energy needed to perform fractional distillation.

What is disillation?
Distillation is a method of separating components of a liquid mixture based on differences in boiling points. The mixture is heated to vaporize the more volatile component, which is then condensed back into a liquid form and collected separately from the less volatile components. It is commonly used in industries such as petrochemicals, food and beverage, and pharmaceuticals for purification and separation purposes.
Why is fractional distillation of petroleum a backwards distillation?
cause it goes upand down. thats how it works

How does low pressure affect distillation?
Lower pressure shifts the boiling point to lower temperatures. Eg. If your ingredience cannot be heated over 60°C you lower the pressure close enough to vacuum (like 200mBar) and the water in your sample evaporetes at lower temperatures. This is not only a rather mild way of distillation, it is also faster than regulation at atmospheric preassure.
