Runny Oil Coursework

Introduction and rough background information

Crude oil is a mixture of substances made from hydrogen and carbon (hydrocarbon), gasoline (petrol) is made from oil.

How Oil Is Made….

It starts of as plankton in the sea

The plankton then dies and falls to the sea bed

The dead plankton is then covered in sand rocks and silt

At this point the plankton is at a low temperature and incredible pressure

The plankton does not decompose completely, due to the lack of oxygen and bacteria

A few million years later oil is formed

It is then split at high temperature into different fuels once extracted from the ground

There are millions of organic chemicals, but they can be divided into groups called homologous series, all members of a homologous series when paired up will have a similar chemical pattern, for instance in the group of alkenes that we will investigate…

Alkenes

I will be working with alkenes and they all follow this pattern ->

Viscosity - Viscosity is how runny something is, if something is more viscose it is thicker, hydro-carbons (hydrogen and carbon) make oil thick, and the more hydrocarbons the thicker something it.

Planning

Aim

I plan to investigate the how the number of hydrocarbons in oil can affect the viscosity of oil, by testing how long it takes to slide down a tile.

My investigation will be done in a laboratory and will involve me measuring a timing how long it takes 5 different oils to travel down a tile at a slant; this angle will be decided after my preliminary trails.

Fair Test

I will make the fair test by examining the various factors involved in my experiment and making sure that they kept fair by only changing one factor.


Factors/Variables

  1. Temperature
  1. Angle of the tile
  1. Amount of oil
  1. The type of oil
  1. How far the oil must travel

Independent factors include things that I cannot change; these include the runniness of the oil.

Join now!

Dependant factors include the amount of oil I will use.

I will control the factors by keeping everything accurate, I will use the same equipment every time so the slightest imperfection in a tile does not affect my experiment, I will use oil from the same source so I am confident that my oil is the same, I will keep the angle of the tile accurate by measuring it with a protractor

Equipment

I have chosen equipment based on my previous knowledge of carrying out experiments and the background information I collected

  1. Ceramic tile – the edges ...
