Essay About Height Of The Tin And Different Alcohols

Investigating Which Alcohol Is the Best Fuel
Essay title: Investigating Which Alcohol Is the Best Fuel
AIM: I am carrying out an investigation to see which alcohol is the
best fuel. I will do this by experimenting with different alcohols and
setting them alight and measuring different factors. I will analyse
all my results and try to discover patterns, which should help me to
conclude which alcohol is the best fuel.
PLAN
====
This is how my experiment will be set out:
Keeping this experiment a fair test
There are many variables in this experiment that can effect the
outcome of this experiment. The dependant variables that I will keep
the same will be the height of the tin can above the wick. I will keep
this the same because different heights can effect the heat that is
transferred to the tin can and into the water, therefore altering the
temperature change. I will use the same tin can so that the experiment
is fair and that different cans may be of different thicknesses so
allowing different amounts of heat through. I will keep the amount of
water that I put inside the tin can, the same for each experiment to
be fair. I will decide on this amount from my preliminary experiment.
The time for each experiment will also be kept the same to ensure the
water has had equal amounts of time for it to heat up, again I will
decide on the time from my preliminary experiment. The independent
variables that I am measuring are the weight of the alcohol in the
burner, both before and after the experiment, and also the temperature
difference from before and after the experiments. I will also make
sure that I take the lid off of the burner as late as possible,
