How does petrol come from crude oil?
It is obtained by fractional distillation, it is a tall enclosed chamber with vents at specific heights from where vapor is extracted to another chamber to liquify it. Its based on the property of specific gravity, when different gases are mixed, the heavier ones stay put near the bottom, thus on boiling crude oil in a tall vessel and determining the height where it stays in the vertical part we can extract the vapours from that section to cool them and we get gas - the term used for petrol. Additionally it can also be obtained by destructive distillation/cracking
Why do petrol and water form heterogeneous mixture?
Petrol and water form a heterogeneous mixture because they do not mix together on a molecular level due to differences in polarity. Petrol is nonpolar, while water is polar, causing them to separate into distinct phases rather than dissolve into each other. This results in the formation of two visibly separate layers when combined.
How can airplane stay up on air?
yh if it has enough petrol
What is the function of the fractionating column in fractional distillation?
The fractionating column is usually filled with glass or plastic beads. These beads improve the separation between the liquids being distilled. The reason that fractional distillation gives better separation between the liquids is because the glass beads in the fractionating column provide "theoretical plates" on which the refluxing liquid can condense, re-evaporate, and condense again, essentially distilling the compound over and over. The more volatile liquids will tend to push towards the top of the fractionating column, while lower boiling liquids will stay towards the bottom, giving a better separation between the liquids.
What is a mixture in which the particles stay suspended in the mixture for an extended time?
suspention
What machine spins to separate a mixture based at different boiling points of its components scientific?
A centrifuge is used to "spin" mixtures and separate them based on their density. Heavier material goes to the bottom and lighter ones stay on top. To separate a mixture based on the boiling points of the ingredients, one can generally use distillation. The two procedures are not used together, so one does NOT use "spinning" to separate items based on the boiling points.
What genre is example stay awake?
'Stay Awake' is a mixture of dance/dubstep
What are three ways to separate the substance in a mixture?
You can separate the substances through filtering, evaporation, and distillation. For example, if you have salt, powdered sulfur and water combined and you want to separate everything, you would mix it all together. Then put filter paper of a cone tube and pour the mixture over it and into a cup. The sulfur granules would stay on top of the filter paper, while the salt dissolves with the water and is poured through with the water. Boil the water until it evaporates, and all that you are left with is salt.
What does it mean if the fuel gauge stay where it is after the engine is turn off?
Does it stay there permanantly? If so check you've filled up with the right fluid; • Petrol • Deisel
How can you recover pure water from dirty dishwater?
You can heat the water using fractional distillation and heat the mixture such that it evaporates. in the fractionating column, cold water can be hosed in to condense the water. the column leads to a beaker where there will be clear or rather clear water. do this a few more times to improve purity (though may not be by much)
How do you separate iodine from ammonium chloride?
first you take water in a beaker and put the mixture in it.you will see that ammonium chloride will dissolve in water because it is highly soluble in water and iodine is not so it won't dissolve. However, the solubility of elemental iodine in water can be increased by the addition of potassium iodide.you can then filter out the mixture so the iodine when you filter will stay on the filter paper. you have got your iodine separated.now for ammonium chloride, you can do evaporation or distillation. To get back water you can do distillation and get distilled water.
How does the Olympic torch stay alight?
Gasoline (petrol). They keep a small flame in a lantern alight at all times between Games.
