Investigating Fuels
Aim;
To find out the heat of combustion in the five fuels;
Methanol,
Ethanol,
Propanol,
Butanol,
Pentanol,
All of these alcohols are apart of the Hydrocarbon chain.
Apparatus;
I will need the following to carry out my investigation for the
Experiment;
Top pan balance - To measure the weight of the fuel.
Clamp Stand - To hold the boiling tube above the crucible.
Boiling tube - To hold 30 cubic centimetres of water in.
Heat proof mat - So the Bunsen burner doesn't burn the table.
Bunsen burner - I need the flame to light the taper.
Measuring cylinder - To measure 30cc of water in.
Mineral wool - So the taper can light the fuel easier.
A stop clock - To time how long the fuel will burn.
Taper - To light the fuel by using the flame from the Bunsen burner.
Ruler - To measure the distance from the crucible to the boiling tube.
Crucible - To carry the mineral wool and fuel in it.

Plan;
First of all, I will set the clamp stand 3.5cm vertically higher then
the crucible which then I put some mineral wool in and 30 drops of the
fuel in. After that I am going to weigh the crucible making sure there
is no other liquid or any other substances on the weigher, so I don't
do not get any anomalous results. After I have recorded the weight I
am going to place the crucible directly under the boiling tube, like
shown in the diagram, and then I am going to pour 30 cubic centimetres
into the measuring cylinder. To make sure I have exactly 30 cubic
centimetres in the cylinder I have to get down on my knee and get my
eye sight level to the mark which is labelled "30cc" to get the
experiment as accurate and reliable as I can. When I am satisfied with
how much water I have got in the cylinder, I will pour it in the
this is the best volume to use as it is about ¾ of a test tube full,
A sampling port for measurement of the sediment concentration was located at 12.7 cm (5 in) from the bottom of the cylinder.
3. Add on of the following volumes of distilled water to the test tube, as assigned by your teacher: 10.0mL, 15.0mL, 20.0mL, 25.0mL, 30.0mL. (If you use a graduated cylinder, remember to read the volume from the bottom of the water meniscus. You can make more a more accurate volume measurement using either a pipette or a burette.)
Palm wine and spices were used to purify the intestines and the liver. The chest and stomach areas would be filled with myrrh, cinnamon, and other herbs. The body would be sewn up and immersed. in natron for seventy days. After seventy days the body would be washed and wrapped in linen from head to foot, bound by a gum-like substance.
Hydrogen lies in one of the copious replacements for gasoline. It is not an energy source such as oil, but an energy carrier that is produced instead of digging and finding it underground. Though replacing fossil fuels by hydrogen fuel cell is very hard and costs a great deal, for the most part, hydrogen fuel cell is a zero carbon emission fuel which highly reduces the carbon emissions that causes pandemic global warming. Hydrogen is very helpful for nature by cause of replacing fossil fuels with hydrogen fuel cells might end global warming once and for all.
Experiment to Find Out Which Fuel Produces Most Energy. Aim = == My objective in this piece of coursework is to determine which of five fuels produces the most energy and if the energy production relates to the amount of carbon..
the same will be the height of the tin can above the wick. I will keep
Start with the hot water and first measure the temperature. Record it. 8. Then pour 40 ml into the beaker. You can measure how much water was used by looking at the meniscus.
Finding Out Which Fuel Releases the Most Energy Per Gram. Aim: To be able to Find out which fuel releases the most energy per gram. Scientific Theory: What is the Science of Heat is the transfer of energy between two objects due to a temperature. The sand is a sand.
8. Continue to heat the crucible, occasionally lifting the lid with tongs to provide oxygen for the reaction
In this report I will explain the fuel systems in an automobile. I will cover different parts and how they work. First thing to do is explain how the fuel system works. The purpose of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air then vaporized and burned to produce energy. The fuel, which can be either gas or diesel is stored in a fuel tank. A fuel pump draws the fuel from the gas tank through lines and brings it through a fuel filter. Next it goes to either a carburetor or fuel injector and then delivered to the cylinder chamber for combustion.

Based on Collins English Dictionary (2003), petrol is defined as any one of various volatile flammable liquid mixtures of hydrocarbons, mainly hexane, heptane, and octane, obtained from petroleum and used as a solvent and a fuel for internal-combustion engines. Currently, the petrol becomes a necessary for everyone especially for user in transportation. Caless, Capel and Leonard (2011) stated that in the late of nineteenth century, a chemical company in London use 'petrol' as their product name.
