Investigating Fuels

Investigating Fuels

To observe temperature change in Ethanol and Methanol.

=======================================================

Introduction (scientific knowledge):

ETHANOL

=======

Ethanol is an alcohol-based alternative fuel produced by fermenting

and distilling starch crops that have been converted into simple

sugars. Ethanol ("Alcohol") C2H5OH

METHANOL

========

Methanol (CH3OH) is an alcohol fuel. Today a process using natural gas

as a feedstock produces most of the world’s methanol.

[IMAGE](CH3OH) also known as methyl alcohol or wood alcohol, it’s a

chemical compound with chemical formula (CH3OH). It is the simplest

alcohol, and is a light, volatile, colourless, flammable, poisonous

liquid that is used as an antifreeze, solvent, and fuel and as a

denaturant for ethyl alcohol and it burns in air forming carbon

dioxide and water.

Prediction:

I predict that Ethanol will be in a higher temperature than Methanol

in the time given to investigate the two fuels.

Fair Test:

To make this investigation a fair test, you’re going to have to make

sure you have all the equipment and that they are up to date,

especially the jug. Put the same amount of into each jug; make sure

the room temperature for both thermometers are the same before burning

the fuels.

Measure the flame and make sure that they are the same size.

Check the temperature at the same time after every 1-minute for 10-

minutes. Repeat this twice to get the average temperature.

You might need someone else to help you and don’t forget to do this

fair test for both Ethanol and methanol.

Safety:

The safety for this experiment is to tie hair back in case of it

catching the flame, clear the table so that only the equipment that

you are using is in sight, to wear goggles at all times, do NOT put

the thermometer or any part of your body anywhere near the flame.

Equipment:

Heat- prove mat, beehive stand, stripod, beaker, goggles, ethanol,
