Chemistry coursework – Fuels



In this investigation I will have to find out which of the alcohol
fuels: methanol, ethanol, propanol and butanol, is the best. The
‘best’ one will be the one which creates the most energy whilst

Introduction and prediction

A fuel is a substance burned for heat or power. The best type of fuel
is one that: can be transported safely without the worry of it
catching on fire, gives out a lot of heat for a certain mass, does not
cost very much, lights quickly, burns slowly, is safe to use and does
not give off any form of polluting gases.

When burning alcohols, as I am going to do in this investigation, the
reaction is exothermic as heat is given out. Breaking the bonds of the
original alcohol by burning requires energy-it is endothermic, making
the bonds of the new products of burning the alcohol ie carbon dioxide
and water gives out energy-it is exothermic.

I predict that Butanol will require the most energy as it has the most
bonds holding the carbon, oxygen and hydrogen atoms together. Propanol
will require the second largest amount of energy, Ethanol the third
and Methanol the least amount of energy to break these bonds.

Methanol CH3OH
Ethanol C2H5OH
Propanol C3H7OH
Butanol C4H9OH
Pentanol C5H10OH

Therefore I predict that Methanol will be the ‘best’ fuel, followed by
Ethanol, then Propanol and the worst fuel will be Buta...

Investigate whether firelighter, wood, ethanol, paraffin or wax contains the most energy

- Investigate whether firelighter, wood, ethanol, paraffin or wax contains the most energy Energy In Different Fuels Aim: I am going to investigate which fuels contain the most energy between; firelighter, wood, ethanol, paraffin and wax. Prediction: I think that the fuel that contains the most energy is the one that produces the highest rise in temperature of the water. I know this because… Heat + fuel + oxygen => CO2 + H20 + energy. The energy realised is heat and light energy, which is dependent on the chemical potential energy in the fuel....   [tags: GCSE Chemistry Coursework Investigation]

Investigation of the Heat Energy Produced by Combustion of Various Alcohols

- Investigation of the heat energy produced by combustion of various Alcohols Aim: ---- To investigate how different alcohols produce different amounts of heat energy through combustion. I will be heating water using different alcohols as fuels and measuring the amount of fuel consumed. From working out how much fuel has been used I can work out how much bond energy has released from the molecules of the alcohol. From those results I will be able to say which alcohol is the best for combustion and which one is the worst to combust....   [tags: GCSE Chemistry Coursework Investigation]

Chemistry and Technology in Biodiesel Essay

- ... The diesel engine was originally intended to run on bio-fuel such as vegetable oil, rather than the petroleum-based diesel fuels mainly used today. Therefore society did not know what it was like to run petroleum-based diesel fuel before biodiesel was invented. Biodiesel gives a cleaner diesel fuel to run in vehicles. It does not give off the bad pollutions like a petroleum-based diesel fuel when burned. Therefore it is affecting society in a positive way, by not polluting the air. The resources to make biodiesel are organic, it is a renewable resource so, practically the resources will never run out to make the fuel so resources do not affect the fuel from being made....   [tags: cleaner fuels for internal combustion engines]

Essay about A Quick Look at Different Fuels and How They Work

- ... You can still find them in cell phones, laptops, and other small devices, but until all tests and procedures are complete they will not be in vehicles or big equipment. The discovery of the hydrogen fuel cell was advanced almost directly from the natural resource of hydrogen and oxygen. Without these there would be no fuel cells. I believe this discovery will be a real breakthrough in society since the resources needed to fuel the cells are generally easy to come by. In my opinion, everyone eventually will convert to this in the future for better quality and more cost efficient in the long run....   [tags: history of chemistry]

History of Chemistry: Medicine and Technology Essay

- ... Also when someone came up with a new type of virus or some symptom or something that needed medical attention, was complicated for them to try and figure what it was or if it was the weather change. But thankfully technology has been improved to help us live better and in a safe environment. Natural resources may limit technology but it also advances technology. In the many ways that it advances or helps technology are that; it reduces or eliminates the use or generation of hazardous substances....   [tags: cures, environment, lives, chemistry]

Essay Nuclear Chemistry

- Types of Radiation: • List the three types of Radiation and describe conditions under which each case occurs. Alpha, Beta, Gamma. Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged. The nuclei are ejected from heavy, unstable nuclei so as to remove excess protons and neutrons. However, the formed nuclei may still be radioactive in which even further decay will occur. Alpha emissions occur in nuclei with atomic numbers greater than 83....   [tags: Chemistry]

Rate of Reaction Coursework Essay

- Rates of Reaction A chemical reaction can only occur between particles when they collide (hit each other). Particles may be atoms, ions or molecules. There is a minimum amount of energy which colliding particles need in order to react with each other. If the colliding particles have less than this minimum energy then they just bounce off each other and no reaction occurs. This minimum energy is called the activation energy. The faster the particles are going, the more energy they have. Fast moving particles are more likely to react when they collide....   [tags: GCSE Chemistry Coursework Investigation]

Organic Chemistry Essay

- Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at first, then in Germany, later on in England....   [tags: Chemistry]
