Science Investigation
AIM:
In this investigation we are going to find out which fuel
contains the most energy by burning each fuel and using its
heat to heat up water.
PREDICTION:
I predict that Ethanol will contain the most energy.
I can backup my answer by referring to my scientific
knowledge,
Ethanol will burn the quickest because it has more energy
stored within its bonds C-C-C .
METHOD:
In this experiment I will change the fuels, I will use
different fuels.
I will use 120ml of water to boil and I will keep that the
same all the way throughout the experiment. I will measure
the temperature of the water before I heat it and I will
use the same amount of fuel each time to keep the
experiment fair, I will also keep it a fair test by heating
the water for the same amount of time for each fuel.
Below is a list of all the equipment which I will need for
my experiment:
*Different types of fuels
*Tin lids
*Thermometer
*Water
*Tripod
The first thing which I will do is weigh the fuels and note
down the results, then I will place a tin lid underneath
the tripod and place the first fuel on the tin, then I will
measure 120ml of water and place it in a beaker on top of
the tripod and w
and then I will burn the fuel and use it to heat up the
water for 2 minutes. After 2 minutes I will weigh the fuel
and take the temperature of the water, I will repeat this
process using all of the fuels and then I will use the
following formula to work out the Energy given out:
Energy = Mass (g) (0.120) X 4200 (SHC) X Temp Change.
To make the experiment safe I will wear goggles to protect
my eyes from any fuel spillage which could damage my eyes.
RESULTS:
I will show my result by drawing various different types of
graphs and tables.
Below are the Energy amounts in J which each fuel gave out:
Meta fuel 6552 J
Ethanol 12096 J
Propane 8064 J
Methanol 9072 J
Peanut 5049 J
To make my results more accurate and fair I measured each
fuel more than once.
>From looking at my results I have found that Ethanol gives
the most energy, which was around 12000 J and then it was
Methanol in secound place. From my results I can say that
my prediction was right and I can say that the reason why
Ethanol made the most energy is because it was the
strongest because it had more energy stored in its bonds.
If I had more time to improve my experiment I would repeat
each fuel several time and I would spend some time
comparing my results with my friends.
