Viscosity of Oils.

Extracts from this document...


Viscosity of oils. (Planning) The runniness of oils. Aim I am going to find out the viscosity of each of the 5 sample oils by testing them to investigate my experiment. Prediction I think the order in which the oils will be the most viscous in and the runniness of each of them, will prove to me the viscosity of the oils. I think the most runny oil will be hexane and the least viscous as well because the numbers of hydrocarbons in it are less, being the thinnest oil from the other 4, I predict that hexane is the most runny oil. I think hexane is the most runny oil because it is the thinnest oil of all and also because all oils come from the death and decay of plants and animals, covered up by layers of mud and sand at high temperatures, which formed fossil fuels such as crude oil. ...read more.


Another thing that makes me think that hexane is the runniest is because all hydrocarbons are bonded together, they share electrons, all of these alkanes have a c-c single bonds, they are made up of chains of carbon atoms with single covalent bonds between them. Example of one natural gas with it's formulae: Methane: CH4 The ways in which these hydrocarbons are bonded have the formulae: Cn H2n+2 from which we can know that they are alkanes and can find out the formulae of everyone of them. Example of one oil, lets see decane. Decane has 10 carbon atoms to find out the formulae, we will use the main formulae: Cn H2n+2 C10 H2 10 + 2 =C 10 H 22 So, I think the bonding of these electrons can prove that how much viscous each of them are? PLANNING Method The diagram above shows my experiment set up. ...read more.


I made my experiment a fair test, to do this I used the same amount of oil (1 drop)every time with all the 5 oils. I also kept the distance and the angle same in the investigation. I took measurements accurately and made my experiment reliable by repeating the results twice and then finding the average to plot the graph. PRELIMINARY WORK In my experiment I used specific amount of oil because I thought if I drop more than one drop of oil on the glass from the pipette than the experiment wouldn't remain fair and also if I would have kept different distances for the oil to travel than the measurement which I would have got Would not be accurate. SAFETY The safe use of apparatus in my experiment was the first priority but as to my investigation there were no out-standing precautions that I had to take in my experiment. ?? ?? ?? ??

  1. Basics of Crude Oil.

    Losing temperature as they rise, they condense into liquids, which flow downward into the higher temperatures and are revaporized. This process continues until the various fractions have achieved the appropriate degrees of purity. The lighter fractions, like butane, gasoline and kerosene, are tapped off from the top of the tower;

    In my preliminary work, I am going to investigate different alcohols and choose which will be the best to use in the experiment. It is important that I choose a suitable and open range of different alcohols with different numbers of carbon atoms.

    Key factors to vary- I am going to change the type of oil I use in each experiment because they all have different sized molecules. Key factors to control- I am going to control how much of the oil I drop out of the pipette, the level of the microscope

    It is made up of between 5 and 10 carbon atom alkanes. Gasoline Used for fuelling motor engines. It is a mixture of between 5 and 12 carbon alkanes and also cycloalkanes and is liquid in form. Kerosine This liquid fuel is used for jet engines and also tractors.
